What is the meaning of MOD value?

Answer 1

"Mod" is often used to indicate the remainder of a division, and it is used that way in programming languages, or in Excel or similar spreadsheets. Thus, for example, mod(10, 3) = 1, since that is the remainder when you divide 10 by 3.

Answer 2

The MOD or modulus value of a number n, with reference to a base k, is the remainder when n is divided by k.Thus, mod(n, k) = r if n=k*m + r where m is an integer and 0<=r

An alternative form of representing this relationship is r = n(mod k).

Often n is an integer while k and r are positive integers.
