IEOR returns the bitwise Boolean exclusive-OR of I and J.
Fortran 90 and later, with boz-literal-constant Fortran 2008 and later, has overloads that are GNU extensions
Elemental function
RESULT = IEOR(I, J)
| 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. |
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 — Convert to integer type occurred.
