Elemental Intrinsic Function (Generic): Performs an exclusive OR on corresponding bits. This function can also be specified as XOR or IXOR.
Syntax
result = IEOR (i, j)
i
(Input) Must be of type integer.
j
(Input) Must be of type integer with the same kind parameter as i.
Results
The result type 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.
| Specific Name | Argument Type | Result Type |
|---|---|---|
| BIEOR 1 | INTEGER(1) | INTEGER(1) |
| IIEOR 2 | INTEGER(2) | INTEGER(2) |
| JIEOR 3 | INTEGER(4) | INTEGER(4) |
| KIEOR 4 | INTEGER(8) | INTEGER(8) |
| 1 Or BIXOR 2 Or HIEOR, HIXOR, or IIXOR 3 Or JIXOR 4 For compatibility, this specific function can also be specified as IXOR. |

Examples
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
The following shows an example using alternate option XOR:
INTEGER i, j, k
i = 3 ! 011
j = 5 ! 101
k = XOR(i, j) ! returns 6 = 110
