9.152 IOR — Bitwise logical or

Description:

IOR returns the bitwise Boolean inclusive-OR of I and J.

Standard:

Fortran 90 and later, with boz-literal-constant Fortran 2008 and later, has overloads that are GNU extensions

Class:

Elemental function

Syntax:

RESULT = IOR(I, J)

Arguments:
I The type shall be INTEGER or a boz-literal-constant.
J The type shall be INTEGER with the same kind type parameter as I or a boz-literal-constant. I and J shall not both be boz-literal-constants.
Return value:

The return type is INTEGER with the kind type parameter of the arguments. A boz-literal-constant is converted to an INTEGER with the kind type parameter of the other argument as-if a call to INT occurred.

Specific names:
