Language Reference

MODULO(A, P)

Modulo function.

A

must be of type integer or real.

P

must be of the same type and kind type parameter as A.

Class

Elemental function

Result Type and Attributes

Same as A.

Result Value

• Case (i): A is of type integer. If P <> 0, MODULO (A, P) has the value R such that A = Q * P + R, where Q is an integer.

  If P > 0, the inequalities 0 <= R < P hold.

  If P < 0, P < R <= 0 hold.

  If P = 0, the result is undefined.

• Case (ii): A is of type real. If P <> 0, the value of the result is A - FLOOR (A / P) * P.

  If P = 0, the result is undefined.

Examples

MODULO (8, 5) has the value 3.

MODULO (-8, 5) has the value 2.

MODULO (8, -5) has the value -2.

MODULO (-8, -5) has the value -3.
