XOR— Bitwise logical exclusive OR
Bitwise logical exclusive or.
This intrinsic routine is provided for backwards compatibility with
GNU Fortran 77. For integer arguments, programmers should consider
the use of the IEOR intrinsic and for logical arguments the
.NEQV. operator, which are both defined by the Fortran standard.
RESULT = XOR(I, J)
|I||The type shall be either a scalar |
|J||The type shall be the same as the type of I or
a boz-literal-constant. I and J shall not both be
boz-literal-constants. If either I and J is a
boz-literal-constant, then the other argument must be a scalar |
The return type is either a scalar
INTEGER or a scalar
LOGICAL. If the kind type parameters differ, then the
smaller kind type is implicitly converted to larger kind, and the
return has the larger kind. 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.
