Decimals

This module provides a single trait for rounding floating-point numbers to a specified number of decimal places. That's all!

This should really be part of the standard library, or at least in the num crate. But it's not!

Examples

use decimals::Decimals;

assert_eq!(1.23456789.round_to(2), 1.23);
assert_eq!(1.23456789.round_to(3), 1.235);
