Intel® Fortran Compiler 16.0 User and Reference Guide
Elemental Intrinsic Function (Generic): Performs an exclusive OR on corresponding bits. This function can also be specified as XOR or IXOR.
result = IEOR (i,j)
i |
(Input) Must be of type integer or of type logical (which is treated as an integer). |
j |
(Input) Must be of type integer with the same kind parameter as i. If the kinds of i and j do not match, the value with the smaller kind is extended with its sign bit on the left and the larger kind is used for the operation and the result. |
The result type and kind is the same as i. The result value is derived by combining i and j bit-by-bit according to the following truth table:
i j IEOR (i, j)
1 1 0
1 0 1
0 1 1
0 0 0
The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.

IEOR (12, 7) has the value 11; binary 1100 exclusive OR with binary 0111 is binary 1011.
The following shows another example:
INTEGER I
I = IEOR(240, 90) ! returns 170
! IEOR (B'11110000', B'1011010') == B'10101010'
The following shows an example using alternate option XOR:
INTEGER i, j, k i = 3 ! B'011' j = 5 ! B'101' k = XOR(i, j) ! returns 6 = B'110'
