gmp_kronecker — Kronecker symbol
This function computes the Kronecker symbol of num1 and
num2.
num1
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
num2
A GMP object, an int,
or a string that can be interpreted as a number following the same logic
as if the string was used in gmp_init() with automatic
base detection (i.e. when base is equal to 0).
Returns the Kronecker symbol of num1 and
num2
