Add y to x

Returns the adjusted modulus of x and y

Returns the quotient and modulo of x over y using a mod function that works with integer and floats

Returns the greatest common divisor of x and y

Returns the least common multiple of x and y

Returns x modulus y but unlike the builtin rem, also works for floats

gcd(x, y)

Returns the greatest common divisor of x and y

lcm(x, y)

Returns the least common multiple of x and y

mod(x, y)
