Decimal Floating Point arithmetic for rust based on the [decNumber

library](http://speleotrove.com/decimal/decnumber.html).

The library provides d128 which is a [128-bit decimal floating

point](https://en.wikipedia.org/wiki/Decimal128_floating-point_format) number.

You can use it as other primitive numbers in Rust. All operators are overloaded

to allow ergonomic use of this type.

To emulate literals a macro is used `d128!`.

[Documentation](https://docs.rs/decimal)

# Example

```rust

let x = d128!(1.234);

let y = d128!(1.111);

let z = d128!(2.345);

assert_eq(x + y, z);

```

# Running the [decTest](http://speleotrove.com/decimal/dectest.html) test suite

```bash

$ cargo build

$ ./target/debug/run-test decTest/decQuad.decTest

```
