Expand description

This trait describes modular arithmetic operations

Required methods

Return (self ^ exp) % m

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.

Calculate Jacobi Symbol (a|n), where a is self

Panics

if n is negative or even

Calculate Kronecker Symbol (a|n), where a is self

Calculate Legendre Symbol (a|n), where a is self.

Note that this function doesn’t perform primality check, since is costly. So if n is not a prime, the result is not reasonable.

Panics

if n is not prime
