8.142 IBSET — Set bit ¶
Synopsis:
RESULT = IBSET(I, POS)
Description:
IBSET returns the value of I with the bit at positionPOS set to one.
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 |
|---|---|---|---|
| IBSET(A) | INTEGER A | INTEGER | Fortran 90 and later |
| BBSET(A) | INTEGER(1) A | INTEGER(1) | GNU extension |
| IIBSET(A) | INTEGER(2) A | INTEGER(2) | GNU extension |
| JIBSET(A) | INTEGER(4) A | INTEGER(4) | GNU extension |
| KIBSET(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)
