Usage

~ expression

Parameters

expression A number.

Returns

None.

Description

Operator (bitwise); converts the expression to a 32-bit unsigned integer, then inverts the bits. A bitwise NOT operation changes the sign of a number and subtracts 1.

Example

The following example shows a bitwise NOT operation performed on a variable.

a = 0;
trace ("when a = 0, ~a = "+~a);
// when a = 0, ~a = -1
a = 1;
trace ("when a = 1, ~a = "+~a);
// when a = 0, ~a = -2
// therefore, ~0=-1 and ~1=-2
