sinum

This Rust crate provides the SiNum type that represents numbers that can easily be represented by the International System of Units (SI, from French Système International).

Example

To use this crate your Cargo.toml could look like this:

[dependencies]
sinum = "0.1.0"

Create a prefix-aware number:

use sinum::{SiNum, Prefix};

let num = SiNum::new( 9.9 ).with_prefix( Prefix::Milli );

assert_eq!( num.as_f64(), 0.0099 );
assert_eq!( num.prefix(), Prefix::Milli );
assert_eq!( format!( "{}", num ), "9.9 m" );

A SiNum prefix can be changed, without changing the value of the number it represents:

use sinum::{SiNum,Prefix};

let num = SiNum::new( 9.9 ).to_prefix( Prefix::Milli );

assert_eq!( num.as_f64(), 9.9 );
assert_eq!( num.prefix(), Prefix::Milli );
assert_eq!( format!( "{}", num ), "9900 m" );
