Returns the floor modulus of the long and int arguments.

The floor modulus is x - (floorDiv(x, y) * y), has the same sign as the divisor y, and is in the range of -abs(y) < r < +abs(y).

The relationship between floorDiv and floorMod is such that:

For examples, see floorMod(int, int).

Parameters:

x the dividend

y the divisor

Returns: the floor modulus x - (floorDiv(x, y) * y)

Exceptions:

ArithmeticException if the divisor y is zero
