Feature gate: #![feature(float_bits_const)]

This is a tracking issue for fN::BITS.

This adds f32::BITS and f64::BITS, (additionally f16::BITS and f128::BITS) constants, analogous to the existing {integer}::BITS.

Public API

impl f32 {
    pub const BITS: u32 = 32;
}

impl f64 {
    pub const BITS: u32 = 64;
}
