IntegerBitNot¶
Bitwise complement of an integer.
Declaración¶
Sintaxis¶
IntegerBitNot(expr arg, ttype type, expr? value)
Argumentos¶
Argument |
Descripción |
|---|---|
|
the operand. |
|
the type of the expression. |
|
the compile time value of the expression, when the frontend could fold it; |
Valores devueltos¶
The value of the expression.
Descripción¶
IntegerBitNot is not(i): every bit of the operand is flipped. It is a
separate node from IntegerUnaryMinus because the two
differ by one for two’s complement integers, and because the bitwise operation
is meaningless for the other numeric types.
