Enum rugflo::Constant

pub enum Constant {
    Log2,
    Pi,
    Euler,
    Catalan,
}

The available floating-point constants.

Examples

use rugflo::{Constant, Float};

let log2 = Float::from((Constant::Log2, 53));
let pi = Float::from((Constant::Pi, 53));
let euler = Float::from((Constant::Euler, 53));
let catalan = Float::from((Constant::Catalan, 53));

assert!(log2.to_string_radix(10, Some(5)) == "6.9315e-1");
assert!(pi.to_string_radix(10, Some(5)) == "3.1416e0");
assert!(euler.to_string_radix(10, Some(5)) == "5.7722e-1");
assert!(catalan.to_string_radix(10, Some(5)) == "9.1597e-1");
