Core unary modular arithmetics

Note that all functions will panic if the modulus is zero.

Required Methods

fn negm(self, m: Modulus) -> Self::Output

Return (-self) % m and make sure the result is normalized in range [0,m)

fn invm(self, m: Modulus) -> Option<Self::Output>

Calculate modular inverse (x such that self*x = 1 mod m).

This operation is only available for integer that is coprime to m. If not, the result will be None.

fn dblm(self, m: Modulus) -> Self::Output

Calculate modular double ( x+x mod m)

fn sqm(self, m: Modulus) -> Self::Output

Calculate modular square ( x*x mod m )
