Crate turns 

Fixed-point angles modulo 2π, backed by unsigned integers.

Angle<T> represents an angle as an unsigned integer where the full range of T maps onto one full turn (2π radians / 360 degrees). Natural integer overflow provides wraparound at 2π, so modular arithmetic is free.

Type aliases Angle8, Angle16, Angle32, Angle64, and Angle128 cover the standard widths.

Precision

Float conversions are generic over any F: Float. Expect precision loss when the integer width exceeds the float mantissa (e.g. Angle128 with f64 keeps ~53 of 128 bits). Non-finite inputs (NaN, infinities) are coerced to zero rather than panicking.

Example

use turns::Angle8;
use core::f64::consts::PI;

let pi = Angle8::from_radians(PI);
assert_eq!(pi + pi, Angle8::from_radians(0.0_f64));
