Crate float_format

Float Format

This is a crate for customizing the format of floating point numbers. This crate is still work in progress, many features are still to be added.

So far everything is unstable.

Example

use float_format::*;
 
fn main() {
    // Create with a custom format and parse from a string.
    let float = Float::from_str(
        Format::new_ieee_excess(16, 64),
        "123456.789012345",
    ).unwrap();
 
    // Format the float with custom precision.
    assert_eq!(format!("{:.8}", float), "123456.78901234");
 
    // Convert from primitive float types.
    assert_eq!(Float::from(0.2f32).to_f32(), 0.2f32);
    assert_eq!(Float::from(0.2f64).to_f64(), 0.2f64);
}
