IBSET

Elemental Intrinsic Function (Generic): Sets one bit to 1.

Syntax

result = IBSET (i, pos)

i
(Input) Must be of type integer.

pos
(Input) Must be of type integer. It must not be negative and it must be less than BIT_SIZE(i).
The rightmost (least significant) bit of i is in position 0.

Results:

The result type is the same as i. The result has the value of the sequence of bits of i, except that bit pos of i is set to 1.

For more information, see Bit Functions.

The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.

Examples

IBSET (8, 1) has the value 10.

If V has the value (1, 2, 3, 4), the value of IBSET (POS = V, I = 2) is (2, 6, 10, 18).

The following shows another example:

INTEGER I
I = IBSET(8, 2) ! returns 12 = 1100
