Crate fixed_decimal
source · [−]Expand description
fixed_decimal is a utility crate of the ICU4X project.
It includes FixedDecimal, a core API for representing numbers in a human-readable form
appropriate for formatting and plural rule selection. It is optimized for operations involving
the individual digits of a number.
Examples
use fixed_decimal::FixedDecimal;
let dec = FixedDecimal::from(250)
.multiplied_pow10(-2)
.expect("Bounds are small");
assert_eq!("2.50", format!("{}", dec));

struct MagnitudeAndDigit(i16, u8);
let digits: Vec<MagnitudeAndDigit> = dec
.magnitude_range()
.map(|m| MagnitudeAndDigit(m, dec.digit_at(m)))
.collect();
assert_eq!(
vec![
MagnitudeAndDigit(-2, 0),
MagnitudeAndDigit(-1, 5),
MagnitudeAndDigit(0, 2)
],
