(Discuss) Proposed since November 2015. MOD is a computer file format used primarily to represent music, and was the first module file format. MOD files use the â.MODâ file extension, except on the Amiga where the original trackers instead use a âmod.â prefix scheme, e.g. âmod.echoingâ.
The mod operator in computer languages is simply the remainder. For example, 17 mod 3 = 2 because 17 / 3 = 5 rem 2 which in turn means 17 = 3 * 5 + 2 There are some tricky issues when negative numbers are used, but that shouldn't ordinarily be necessary. In math (number theory), the term is used a little differently. The modulus is actually not the remainder, but the number you are dividing by; and mod is not an operator, but a label telling in what sense two quantities are considered congruent, or equal..
