Function arg [src]

Returns the angular component (in radians) of z.

Prototype

pub fn arg(z: anytype) @TypeOf(z.re, z.im)

Example

 test arg {
    const epsilon = math.floatEps(f32);
    const a = Complex(f32).init(5, 3);
    const c = arg(a);
    try testing.expectApproxEqAbs(0.5404195, c, epsilon);
}

Source

  pub fn arg(z: anytype) @TypeOf(z.re, z.im) {
    return math.atan2(z.im, z.re);
}
