The Not operator performs a bitwise negation on its operand. 

 not-operator-expression = "not" expression

Runtime semantics:

§ The operation to produce the result is determined based on the values of the operand, as follows:

Operand Value

Result

Integral value

Bitwise Not of operand

Null

Null

 

§ If a bitwise Not of the operand is indicated, the result is produced by generating a corresponding result bit for each identically positioned bit in the implementation format of the operand according to the following table:

Operand Bit

Result Bit
