A function that returns the remainder found from dividing a number by a divisor is known as a MOD function (or modulo function). In other words, it returns the remainder from dividing by some number. For example, in Excel, the formula =MOD(10, 3) returns 1, for the reason that 10 divided by 3 is 3 with a remainder of 1, according to the documentation for Excel.Hope this helps you
