Elemental Intrinsic Function (Generic): Returns the remainder when the first argument is divided by the second argument.
Syntax
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.
Results
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.
