Enum rug::float::Constant
[−]
[src]
pub enum Constant { Log2, Pi, Euler, Catalan, }
The available floating-point constants.
Examples
use rug::Float; use rug::float::Constant; let log2 = Float::with_val(53, Constant::Log2); let pi = Float::with_val(53, Constant::Pi); let euler = Float::with_val(53, Constant::Euler); let catalan = Float::with_val(53, Constant::Catalan); assert_eq!(log2.to_string_radix(10, Some(5)), "6.9315e-1"); assert_eq!(pi.to_string_radix(10, Some(5)), "3.1416"); assert_eq!(euler.to_string_radix(10, Some(5)), "5.7722e-1"); assert_eq!(catalan.to_string_radix(10, Some(5)), "9.1597e-1");
