128-bit wide floating point implementation for Rust

Installation

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 and MongoDB Decimal128 BSON type. The following methods are currently implemented:

• Decimal128.from_raw_bytes
• Decimal128.zero
• Decimal128.is_nan
• Decimal128.is_negative
• Decimal128.is_zero
• Decimal128.to_string

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);
