README
decimal 128
128-bit wide floating point implementation for Rust
## Installation
```shell
cargo add decimal128
```
## Usage
This crate is a work-in-progress and does not have all applicable methods implemented as per [IEEE Standard for Floating-Point Arithmetic](https://ieeexplore.ieee.org/document/4610935) and [MongoDB Decimal128 BSON type](https://github.com/mongodb/specifications/blob/master/source/bson-decimal128/decimal128.rst). The following methods are currently implemented:
- `Decimal128.from_raw_bytes`
- `Decimal128.zero`
- `Decimal128.is_nan`
- `Decimal128.is_negative`
- `Decimal128.is_zero`
- `Decimal128.to_string`
```rust
use decimal128;
let vec: [u8; 16] = [
0xf8, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,
0x00,
];
let dec128 = Decimal128::from_raw_buf(vec);
let string = dec128.to_string();
assert_eq!("-Infinity".to_string(), string);
```
