MOD

Syntax

mod::=

Text description of mod

Purpose

MOD returns the remainder of m divided by n. Returns m if n is 0.

Example

The following example returns the remainder of 11 divided by 4:

SELECT MOD(11,4) "Modulus" FROM DUAL;

   Modulus
----------
         3

This function behaves differently from the classical mathematical modulus function when m is negative. The classical modulus can be expressed using the MOD function with this formula:

m - n * FLOOR(m/n)

The following table illustrates the difference between the MOD function and the classical modulus:

M	N	MOD(M,N)	Classical Modulus
11	4	3	3
11	-4	3	-1
-11	4	-3	1
-11	-4	-3	-3
