1. INTRODUCTION
===============

This package contains the release 2.0 Update 2(or V2.2) of the Intel(R) Decimal
Floating-Point Math Library, conforming to the IEEE Standard 754-2008 for
Floating-Point Arithmetic. This is an extension of Release 2.0 Update 1 (or V2.1) of 2011.

The library implements the functions defined for decimal floating-point
arithmetic operations in the IEEE Standard 754-2008 for Floating-Point
Arithmetic, which is a revision of the IEEE Standard 754-1985 for Binary
Floating-Point Arithmetic.

The IEEE Standard 754-2008 for Floating-Point Arithmetic supports two
encoding formats: the decimal encoding format, and the binary encoding format.
The Intel(R) Decimal Floating-Point Math Library supports primarily the binary
encoding format for decimal floating-point values, but the decimal encoding
format is supported too in the library, by means of conversion functions
between the two encoding formats.

Release 2.2 of the library contained in this package implements all
the operations mandated by the IEEE Standard 754-2008. Alternate exception
handling (not a mandatory feature) is not supported currently in the library,
but the design facilitates adding it in the future. It is worth noting that
several useful functions (not part of the IEEE 754-2008 definition) are
provided in LIBRARY/src/bid_round.c. They can be used to round a q-digit decimal
integer number represented in binary to q - x digits (1 <= x <= q - 1).

For operations involving integer operands or results, the library supports
signed and unsigned 8-, 16-, 32-, and 64-bit integers.

Note: Release 2.0 added transcendental functions (supported in 128-bit, 64-bit,
and 32-bit decimal formats), including the ones specified in the technical
report on decimal arithmetic ISO/IEC TR 24732 (available from www.iso.org).
These functions are not correctly rounded, a fact that should be considered
when using them (similary, binary floating-point mathematical functions
implemented for example in C or other compiler math libraries are in general
not correctly rounded either).

2. PACKAGE CONTENTS
===================

This package contains:

- eula.txt, a copy of the end user license agreement that applies to
everything in this package

- this README FILE

- the LIBRARY subdirectory with all the source files necessary to build the
library, and a README file which specifies how to build the library
in Linux**, HP-UX**, Windows***, and other operating systems; a small set
of command files (RUNLINUX, RUNWINDOWS, etc.) can be used to build the
library with different options

- the TESTS subdirectory with source and input files necessary to build and
run a reduced set of tests for the library, and a README
file which specifies how to build and run these tests;
the test program will print the number of errors detected;
note that tests involving 80-bit binary floating-point values (these are
only conversions to and from decimal floating-point formats) are skipped
if the 80-bit floating-point data type is not supported; a small set
of command files (RUNLINUX, RUNWINDOWS, etc.) can be used to build and
run the tests with different options

- the EXAMPLES subdirectory containing eight examples of calls to library
functions with various combinations of build options (see Section 8
below); a README file is included; a small set of command files (RUNLINUX,
RUNWINDOWS, etc.) can be used to build and run the examples with different
options

3. FUNCTION NAMES
=================

The function names used in the library are not identical to the names from
the IEEE Standard 754-2008 for Floating-Point Arithmetic. The mapping between
the two sets is given in Section 10 below. The function names can be changed
by editing the #define statements at the beginning of bid_conf.h.

4. LIBRARY BUILD OPTIONS
========================

The API for the library functions is intended to support constant modes,
global dynamic modes, and scoped dynamic modes. It should be convenient for
compilers with various requirements, even where default modes and no flag
tests can be assumed, as in C99 FENV_ACCESS OFF.

Three build options are provided, that can be set by editing
LIBRARY/src/bid_conf.h, or (more conveniently) can be set on the compile
command line.

(a) Function arguments and return values can be passed by reference if
DECIMAL_CALL_BY_REFERENCE is set to 1, or by value otherwise. However, the
floating-point status flags argument is passed by reference even when
DECIMAL_CALL_BY_REFERENCE is 0, unless it is stored in a global variable
(see (c) below).

(b) The value of the rounding mode can be passed by reference or by value,
or it can be stored in a global variable if DECIMAL_GLOBAL_ROUNDING is
set to 1.
If DECIMAL_GLOBAL_ROUNDING is set to 1 then the rounding mode is stored
in a global variable that must be declared as

_IDEC_round __bid_IDEC_glbround;

In this case __bid_IDEC_glbround is a fixed name that *must* be used (but
it can be changed by editing the corresponding #define in bid_conf.h). Its
initial value should be ROUNDING_TO_NEAREST (or an equivalent value with a name
chosen by the user, as shown in code samples from EXAMPLES where
_IDEC_nearesteven is used). The _IDEC_round type name can be different
(but equivalent), chosen by the user.

(c) The value of the exception status flags is passed by reference if
they are not represented by a global variable, or it can be stored in a
global variable if DECIMAL_GLOBAL_EXCEPTION_FLAGS is set to 1.
If DECIMAL_GLOBAL_EXCEPTION_FLAGS is set to 1 then the exception status
flags are stored in a global variable that must be declared as

_IDEC_flags __bid_IDEC_glbflags;

In this case __bid_IDEC_glbflags is a fixed name that *must* be used but
it can be changed by editing the corresponding #define in bid_conf.h). Its
initial value should be EXACT_STATUS (or an equivalent value with a name chosen
by the user, as shown in code samples from EXAMPLES where _IDEC_allflagsclear
is used). The _IDEC_flags type name can be different (but equivalent),
chosen by the user.

The three build options supported in this release are selected on the
'make' command line when building the library in LIBRARY and the tests in
TESTS using the makefile-s provided here (so editing bid_conf.h is not
necessary). For example when using the Intel(R) C++ Compiler in Linux**:

make CC=icc CALL_BY_REF=0 GLOBAL_RND=0 GLOBAL_FLAGS=0 UNCHANGED_BINARY_FLAGS=0

selects parameter passing by value; the rounding mode is a parameter
passed to each function that requires it; the status flags are passed
as a parameter to functions that may modify them (note however that the
status flags represent an exception in that the CALL_BY_REF setting
is ignored - if not global, they are always passed by reference); the
decimal operations may change the inexact binary status flag.

Another example, when using the Intel(R) C++ Compiler in Windows*** is:

nmake -fmakefile.mak CC=icl CALL_BY_REF=1 GLOBAL_RND=1 GLOBAL_FLAGS=1 UNCHANGED_BINARY_FLAGS=1

where parameters are passed by reference; the rounding mode is a global
variable; the status flags are stored in a global variable; the
decimal operations will not change the inexact binary status flag.

5. FUNCTION PROTOTYPES
======================

Function prototypes are provided in LIBRARY/src/bid_functions.h (starting at
line 396 if parameters are passed by reference, and at line 2994 if they
are passed by value).

6. TESTING
==========

The library was tested on several different platforms (IA-32 Architecture,
Intel(R) 64, and IA-64 Architecture running Linux**, Windows***, HP-UX**,
Solaris**, and OSX**). For example in Linux** icc (Intel(R) C++ Compiler 9.1
or newer) and gcc** were used. In Windows*** icl (Intel(R) C++ Compiler 9.1
or newer) and cl (Microsoft*** Visual C++ Compiler) were used. For each of
these combinations eight combinations of parameter passing method and global
or local rounding mode and status flags were tested.

In limited situations, it is possible for incorrect compiler behavior to
lead to incorrect results in the Intel(r) Decimal Floating-Point Math Library.
For example, results of round-to-integer functions are incorrect when the
library is built using gcc 4.2/4.3. Also, some gcc versions in an IA-32
Linux environment cause slightly incorrect results in a few corner cases for
the 64-bit decimal square root. (This is not an exhaustive list.) Such errors
should be caught by the tests provided with the library.

7. USAGE EXAMPLES
=================

Eight usage examples are given in the EXAMPLES subdirectory, which illustrate
calls to library functions with various combinations of build options (see
Section 4 above). A README file is included. Note that these examples do not
use any include files from the library: the necessary data types are defined
instead directly in the user-defined decimal.h. However, if the rounding mode
or exception status flags are stored in global variables, then these must have
the fixed names of _IDEC_glbround and _IDEC_glbflags.
Alternatively - and this is the preferred method, one could use the data
types defined in the library by including two header files (and in this case
DECIMAL_CALL_BY_REFERENCE, DECIMAL_GLOBAL_ROUNDING, and
DECIMAL_GLOBAL_EXCEPTION_FLAGS would have to be properly defined not only when
building the library, but also for the application calling the library
functions):

#include "../LIBRARY/src/bid_conf.h"
#include "../LIBRARY/src/bid_functions.h"

Such an example is represented by the readtest program in TESTS/readtest.c.

8. DECIMAL AND BINARY STATUS FLAGS
==================================

The IEEE Standard 754-2008 specifies distinct rounding modes for binary
and for decimal floating-point operations. However, the floating-point status
flags may be identical for decimal and binary computations. In this
implementation of the decimal arithmetic, the decimal floating-point status
flags are kept separate from the binary flags. Still, it is possible to merge
the two sets (outside the library).
One issue that needs to be pointed out is that the current implementation of
the decimal floating-point library may set the binary inexact status flag for
certain operations: division, square root, and several other operations where
integers are converted to floating-point values, and the conversion
is inexact. In order to avoid setting the binary inexact flag by decimal
functions, uncomment the following line in bid_conf.h
prior to building the library:
// #define UNCHANGED_BINARY_STATUS_FLAGS

9. MAPPING OF IEEE 754-2008 NAMES TO INTEL (R) DECIMAL FLOATING-POINT MATH
LIBRARY FUNCTION NAMES
=========================================================================

Operand and result types are included, where:
BID64 = the 64-bit decimal floating-point format using the binary
encoding; this becomes BID_UINT64 in the library
BID128 = the 128-bit decimal floating-point format using the binary
encoding ; this becomes BID_UINT128 in the library
binary32 = 32-bit binary floating-point data format
binary64 = 64-bit binary floating-point data format
binary80 = 80-bit binary floating-point data format
binary128 = 128-bit binary floating-point data format
string = char *
boolean = int
enum = int
_IDEC_flags = int
_IDEC_round = int

The library function names shown here can be changed by editing #define
statements in bid_conf.h.

10. DESCRIPTION OF THE INTEL(R) DECIMAL FP MATH LIBRARY FUNCTIONS

This section gives brief descriptions of the functions available in the
Intel(R) Decimal Floating-Point Math Library v2.2. The prototypes are
shown assuming all arguments are passed by value; the rounding mode variable is
passed as an argument to each function that requires it; a pointer to a
variable containing the status flags is passed to each function that requires
it; alternate exception handling is not supported. The function prototypes
for other variants allowed for building the library can be determined from
header files bid_functions.h and bid_conf.h, which contain also all the type
definitions used in the following description, as well as the possible values of
the rounding mode variable rnd_mode and the positions of the individual status
flags in the status word *pfpsf.

Notes:
1. Three decimal floating-point formats are supported, as defined in
IEEE Standard 754-2008: 32-bit, 64-bit, and 128-bit.
The data types used in the library for entities in the three formats are
UINT32, UINT64, and UINT128 which can be mapped externally to types of
appropriate sizes and alignments but having different names, for example
_Decimal32, _Decimal64, and _Decimal128.
The maximum number of decimal digits in the significand of numerical
values represented in these three formats are:
P = 7 decimal digits for the 32-bit decimal floating-point format
P = 16 decimal digits for the 64-bit decimal floating-point format
P = 34 decimal digits for the 128-bit decimal floating-point format
The ranges for normal decimal floating-point numbers are (in magnitude):
1.000000 * 10^(-95) <= x <= 9.999999 * 10^96 for 32-bit format
1.0...0 * 10^(-383) <= x <= 9.9...9 * 10^384 for 64-bit format
(15 decimal digits in the fractional part of the significand)
1.0...0 * 10^(-6143) <= x <= 9.9...9 * 10^6144 for 128-bit format
(33 decimal digits in the fractional part of the significand)
The ranges for subnormal decimal floating-point numbers are (in magnitude):
0.000001 * 10^(-95) <= x <= 0.999999 * 10^(-95) for 32-bit format
0.0...01 * 10^(-383) <= x <= 0.9...9 * 10^(-383) for 64-bit format
(15 decimal digits in the fractional part of the significand)
0.0...01 * 10^(-6144) <= x <= 0.9...9 * 10^(-6144) for 128-bit format
(33 decimal digits in the fractional part of the significand)
Operations with decimal floating-point results usually choose one
representation of the result from among several possible that have the
same numerical value (constituting a 'cohort'). The chosen representation
must have the 'preferred exponent' specified in the IEEE Standard 754-2008.
(For example 1.0 * 10^(-2) + 10.0 * 10^(-3) = 20.0 * 10^(-3), and not
2.0 * 10^(-2).)
The encoding methods for decimal floating-point values are not explained
here. Decimal floating-point values can be encoded using the
string-to-decimal conversion functions (__bid64_from_string and
__bid128_from_string), or decoded using the decimal-to-string conversion
functions (__bid64_to_string and __bid128_to_string).
2. The acronym 'dpd' or 'DPD' is used to identify the decimal encoding method
for decimal floating-point values, defined in the IEEE Standard 754-2008.
The acronym 'bid' or 'BID' is used to identify the binary encoding method
for decimal floating-point values, defined in the IEEE Standard 754-2008.
3. The library functions that operate on decimal floating-point values do so on
values encoded in BID format.
4. The floating-point status flags for inexact result, underflow, overflow,
division by zero and invalid operation are denoted by P, U, O, Z, I
respectively

Note that the function names can be changed by editing #define statements in
bid_conf.h.
