gmp_kronecker — Kronecker symbol

### Description

gmp_kronecker(GMP|int|string `$num1`, GMP|int|string `$num2`): int

This function computes the Kronecker symbol of `num1` and `num2`.

### Parameters

`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).

### Return Values

Returns the Kronecker symbol of `num1` and `num2`
