IOR

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

result = IOR (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.

Results

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   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.
