Trait Float

pub trait Float {
    const MANTISSA_BITS: usize;
    const EXP_BITS: usize;
    const EMAX: i32 = _;

    // Required method
    fn from_fp(neg: bool, mantissa: u64, exp2: u32) -> Self;
}

A trait for IEEE754 floating point numbers.

Required Associated Constants

const MANTISSA_BITS: usize

The bit length of mantissa part.

const EXP_BITS: usize

The bit length of exponent part.

Provided Associated Constants

const EMAX: i32 = _

The exponent bias (the default is (1 << (Self::EXP_BITS - 1)) - 1).

Required Methods

fn from_fp(neg: bool, mantissa: u64, exp2: u32) -> Self

Produce the float from a sign, a mantissa, and a biased exponent.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
