IOR

Elemental Intrinsic Function (Generic): Performs an inclusive OR on corresponding bits. This function can also be specified as OR.

Syntax

result = IOR (i, j)

i
(Input) Must be of type 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 zeros on the left and the larger kind is used for the operation and the result.

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   IOR (i, j)

  1   1       1
  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
BIOR	INTEGER(1)	INTEGER(1)
IIOR ¹	INTEGER(2)	INTEGER(2)
JIOR	INTEGER(4)	INTEGER(4)
KIOR	INTEGER(8)	INTEGER(8)
¹ Or HIOR.

Examples

IOR (1, 4) has the value 5.

IOR (1, 2) has the value 3.
