Example

```rust extern crate twiddle;

use twiddle::Twiddle;

struct UnpackedF32 { negative: bool, exponent: i16, fraction: u32, }

impl From for UnpackedF32 { fn from(f: f32) -> UnpackedF32 { let b = unsafe { std::mem::transmute::(f) }; UnpackedF32 { negative: b.bit(31), exponent: (b.bits(30..23) as i16) - 127, fraction: b.bits(22..0) } } }

fn main() { for f in (-5..6) { let u = UnpackedF32::from(f as f32); println!("{:+} = {}1.{:023b} * 2^{}", f, match u.negative { false => "+", true => "-" }, u.fraction, u.exponent ); } } ```
