Struct Float32 

pub struct Float32(pub f32);

A 32-bit ieee-754 single-precision binary floating-point number (w), from the set $\R$, also known as F32.

The range of valid numeric values is $\lbrack$f32::MIN $\dots$ f32::MAX$\rbrack$.

It is comprised of 1 sign bit, 8 exponent bits, and 23 significand bits.
