Module value

Represents a float value using its mantissa and unit Prefix in a base.

With base = 1000, 1k = 1000, 1M = 1_000_000, 1m = 0.001, 1µ = 0.000_001, etc.

..	..	15	Prefix::Peta
..	..	18	Prefix::Exa
..	..	21	Prefix::Zetta

The base is usually 1000, but can also be 1024 (bibytes).

With base = 1024, 1ki = 1024, 1Mi = 1024 * 1024, etc.

Example

use std::convert::From;
use si_scale::{base::Base, value::Value, prefix::Prefix};

let actual = Value::from(0.123);
let expected = Value {
    mantissa: 123f64,
    prefix: Prefix::Milli,
    base: Base::B1000,
};
assert_eq!(actual, expected);
