Struct GaussSum 

pub struct GaussSum {
    pub re: f64,
    pub im: f64,
}

A normalized complex Gauss sum, kept dependency-free.

Fields

re: f64

Real component.

im: f64

Imaginary component.

Implementations

impl GaussSum

pub fn abs(&self) -> f64

Complex modulus.

pub fn phase_mod8(&self, tol: f64) -> Option<i128>

Phase as an eighth-root index: 0 for 1, 1 for exp(pi*i/4), … . Returns None if the magnitude or angle is not close to an eighth root.
