MODULO

Elemental Intrinsic Function (Generic): Returns the modulo of the arguments.

result = MODULO (a,p)

a

(Input) Must be of type integer or real.

p

(Input) Must have the same type and kind parameters as a. It must not have a value of zero.

Results

The result type is the same a. The result value depends on the type of a, as follows:

If p is equal to zero (regardless of the type of a), the result is undefined.

Example

MODULO (7, 3) has the value 1.

MODULO (9, -6) has the value -3.

MODULO (-9, 6) has the value 3.

The following shows more examples:

 INTEGER I
 REAL R
 I= MODULO(8, 5)         ! returns 3          Note: q=1
 I= MODULO(-8, 5)        ! returns 2          Note: q=-2
 I= MODULO(8, -5)        ! returns -2         Note: q=-2
 I= MODULO(-8,-5)        ! returns -3         Note: q=1
 R= MODULO(7.285, 2.35)  ! returns 0.2350001  Note: q=3
 R= MODULO(7.285, -2.35) ! returns -2.115     Note: q=-4
