modulus
The modulus-function computes the remainder of a division, which is the "leftover" of an integral division.
floor
The floor-function provides the lower-bound of integral division. The upper-bound is computed by the ceil function. (Basically speaking, the floor-function cuts off all decimals).

Floor will round the decimal down and uses the / operator in most languages I know
eg.
5 / 2 = 2 no decimal after the 2
Modulo division returns the remainder and uses the % operator
5 % 2 = 1
