`mod``x`procedure- x
- exact rational

Converts a rational number

`x`to a natural number less than the current modulus.If

`x`is an integer, this is equivalent to`(modulo x n)`. If`x`is a fraction, an integer input is generated by multiplying its numerator by its denominatorâ€™s modular inverse.Examples:

> (with-modulus 7 (mod (* 218 7))) 0 > (with-modulus 7 (mod 3/2)) 5 > (with-modulus 7 (mod/ 3 2)) 5 > (with-modulus 7 (mod 3/7)) Error: (modular-inverse) bad argument type - not coprime to modulus 7: 7
