MOD
The MOD function returns the remainder from a division.
MOD(dividend, divisor)
 dividend: A number to be divided by another number. dividend is a number value.
 divisor: A number to divide into another number. divisor is a number value. If 0, a
division by zero will result and the function will return an error.
Usage Notes
The sign of the result matches that of the divisor. Â
When computing MOD(a, b), MOD gives a number r such that a = bk + r, where r is Â
between 0 and b, and k is an integer.
MOD(a, b) is equivalent to a–b*INT(a/b).

=MOD(6, 3) returns 0.
=MOD(7, 3) returns 1.
