| Description: | Clears one bit to zero. | ||
| Class: | Elemental function; Generic | ||
| Arguments: | I | 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 on bit functions, see Section 9.2.3. The model for the interpretation of an integer value as a sequence of bits is shown in Section D.3. | ||
| Specific Name | Argument Type | Result Type |
|---|---|---|
| INTEGER(1) | INTEGER(1) | |
| IIBCLR | INTEGER(2) | INTEGER(2) |
| JIBCLR | INTEGER(4) | INTEGER(4) |
| KIBCLR | INTEGER(8) | INTEGER(8) |
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).
