Elemental Intrinsic Function (Generic): Returns the remainder when the first argument is divided by the second argument.
result = MOD (a, p)
a |
(Input) Must be of type integer or real. |
p |
(Input)Must have the same type and kind parameters as a. |
The result type is the same as a. If p is not equal to zero, the value of the result is a- INT( a/ p) * p. If p is equal to zero, the result is undefined.

MOD (7, 3) has the value 1.
MOD (9, -6) has the value 3.
MOD (-9, 6) has the value -3.
The following shows more examples:
INTEGER I
REAL R
R = MOD(9.0, 2.0) ! returns 1.0
I = MOD(18, 5) ! returns 3
I = MOD(-18, 5) ! returns -3
