# fixed_decimal [![crates.io](https://img.shields.io/crates/v/fixed_decimal)](https://crates.io/crates/fixed_decimal)
`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
```rust
use fixed_decimal::FixedDecimal;
let dec = FixedDecimal::from(250).multiplied_pow10(-2);
assert_eq!("2.50", format!("{}", dec));
#[derive(Debug, PartialEq)]
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)
],
digits
);
```
