IBCLR

Elemental Intrinsic Function (Generic): Clears one bit to zero.

Syntax

result = IBCLR (i, pos)

i
(Input) Must be of type integer.

pos
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 zero.

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

IBCLR (18, 1) has the value 16.

If V has the value (1, 2, 3, 4), the value of IBCLR (POS = V, I = 15) is (13, 11, 7, 15).

The following shows another example:

INTEGER J, K
J = IBCLR(7, 1) ! returns 5 = 0101
K = IBCLR(5, 1) ! returns 5 = 0101
