Expand description

§to_fixed(x, decimal_places)

Fixation Function

The to_fixed function converts a floating-point number x to a string with a specified number of decimal places, returning a fixed-point string representation.

§Examples

use mathlab::math::{to_fixed, fix, is_nan_f64, INF_F64 as inf, NAN_F64 as NaN};
assert_eq!(to_fixed(0.5235987755982988, 3), "0.524");
assert_eq!(to_fixed(0.5235987755982928, 15), "0.523598775598293");
assert_eq!(to_fixed(0.5235987755982928, 1), "0.5");
assert_eq!(to_fixed(0.5235987755982928, 0), "1");
assert_eq!(to_fixed(0.0, 0), "0");
assert_eq!(to_fixed(inf, 0), "inf");
assert_eq!(to_fixed(inf, 0), "inf");
assert_eq!(to_fixed(NaN, 0), "NaN");
assert!(is_nan_f64(fix(NaN, 0)));
assert_eq!(to_fixed(0.1 + 0.2, 15), "0.3");
