Examples

Check float point numbers

use russell_chk::*;

fn main() {
    assert_approx_eq!(0.123456789, 0.12345678, 1e-8);
    assert_approx_eq!(0.123456789, 0.1234567, 1e-7);
    assert_approx_eq!(0.123456789, 0.123456, 1e-6);
    assert_approx_eq!(0.123456789, 0.12345, 1e-5);
    assert_approx_eq!(0.123456789, 0.1234, 1e-4);
}

Check a vector of float point numbers

use russell_chk::*;

fn main() {
    let a = [0.123456789, 0.123456789, 0.123456789];
    let b = [0.12345678,  0.1234567,   0.123456];
    assert_vec_approx_eq!(&a, &b, 1e-6);
}
