8.145 IEOR — Bitwise logical exclusive or

Synopsis:

RESULT = IEOR(I, J)

Description:

IEOR returns the bitwise Boolean exclusive-OR of I and J.

Class:

Elemental function

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

The return type is with the kind type parameter of the arguments. A boz-literal-constant is converted to an INTEGER or UNSIGNED with the kind type parameter of the other argument as-if a call to INT — Convert to integer type or UINT – Convert to UNSIGNED type, respectively, occurred.
