Big Decimal Math

=============

 

This unit provides an arbitrary precision BCD float number type. The usecase is performing a few arithmetic operations with the maximal possible accuracy and precision, e.g. calculating the sum of numbers from a text files, where the conversion from decimal input to binary floats would take more time than the calculation.

It can be used like any numeric type and supports:

* At least numbers between 10-2147483647 to 102147483647 with 2147483647 decimal digit precision

* All standard arithmetic and comparison operators

* Rounding functions (floor, ceil, to-even, ..)

* Some more advanced operations, e.g. power and sqrt

* Accurate and precise binary float (single/double/extended) to BCD float and string conversion

* ..
