8.140 IBCLR — Clear bit ¶
Synopsis:
RESULT = IBCLR(I, POS)
Description:
IBCLR returns the value of I with the bit at positionPOS set to zero.
Class:
Elemental function
Arguments:
| I | The type shall be INTEGER or UNSIGNED. |
|---|---|
| POS | The type shall be INTEGER. |
Return value:
The return value is of the same type as I.
Specific names:
| Name | Argument | Return type | Standard |
|---|---|---|---|
| IBCLR(A) | INTEGER A | INTEGER | Fortran 90 and later |
| BBCLR(A) | INTEGER(1) A | INTEGER(1) | GNU extension |
| IIBCLR(A) | INTEGER(2) A | INTEGER(2) | GNU extension |
| JIBCLR(A) | INTEGER(4) A | INTEGER(4) | GNU extension |
| KIBCLR(A) | INTEGER(8) A | INTEGER(8) | GNU extension |
Standard:
Fortran 90 and later, has overloads that are GNU extensions. Extension for UNSIGNED (see Unsigned integers)
