8.208 NOT — Logical negation ¶
Synopsis:
RESULT = NOT(I)
Description:
NOT returns the bitwise Boolean inverse of I.
Class:
Elemental function
Arguments:
| I | The type shall be INTEGER or UNSIGNED. |
|---|
Return value:
The return type is INTEGER, of the same kind as the argument.
Specific names:
| Name | Argument | Return type | Standard |
|---|---|---|---|
| NOT(A) | INTEGER A | INTEGER | Fortran 95 and later |
| BNOT(A) | INTEGER(1) A | INTEGER(1) | GNU extension |
| INOT(A) | INTEGER(2) A | INTEGER(2) | GNU extension |
| JNOT(A) | INTEGER(4) A | INTEGER(4) | GNU extension |
| KNOT(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)
