Bitwise NOT operator (~)

Operation

Performs a bitwise "Non" (inverse) of an expression.

result = ~ expression

Parameters

Result

Any variable .

Expression

Any expression .

Description

All unary operators, such as the ~ operator, use the following rules to find the value of an expression:

• If it is used for undefined or null expressions, a run-time error is generated.
• object is converted to a string.
• If possible, the string is converted to a number. If not, a run-time error is generated.
• The Boolean value is treated as a number (0 if False, or 1 if true).

Use this operator to generate a number.

The ~ operator looks at the value of the binary representation of the expression and performs a bitwise NON operation. The results of this operation are as follows:

0101   (expression)----1010   (result)

If any one in the expression is 1, the corresponding bit in the result becomes 0. If any one in the expression is 0, the corresponding bit in the result becomes 1.
