numcmp
This crate is a fork of
num-cmp
but with stable i128 support.
The NumCmp
trait for comparison between differently typed numbers.
use std::f32;
use std::cmp::Ordering;
use numcmp::NumCmp;
assert!(NumCmp::num_eq(3u64, 3.0f32));
assert!(NumCmp::num_lt(-4.7f64, -4i8));
assert!(!NumCmp::num_ge(-3i8, 1u16));
// 40_000_000 can be exactly represented in f32, 40_000_001 cannot
assert_eq!(NumCmp::num_cmp(40_000_000.0f32, 40_000_000u32), Some(Ordering::Equal));
assert_ne!(NumCmp::num_cmp(40_000_001.0f32, 40_000_001u32), Some(Ordering::Equal));
assert_eq!(NumCmp::num_cmp(f32::NAN, 40_000_002u32), None);
