~expression
Also known as the one's complement operator or the bitwise complement operator. Converts
the expressionto a 32-bit signed integer, and then applies a bitwise one's complement. That
is, every bit that is a 0 is set to 1 in the result, and every bit that is a 1 is set to 0 in the result.
The result is a signed 32-bit integer.
For example, the hex value 0x7777 is represented as this binary number: 0111011101110111
The bitwise negation of that hex value, ~0x7777, is this binary number: 1000100010001000
In hexadecimal, this is 0x8888. Therefore, ~0x7777 is 0x8888.
The most common use of bitwise operators is for representing flag bits (Boolean values packed
into 1 bit each).
Floating-point numbers are converted to integers by discarding any digits after the decimal
point. Positive integers are converted to an unsigned hex value with a maximum value of
4294967295 or 0xFFFFFFFF; values larger than the maximum have their most significant
digits discarded when they are converted so the value is still 32-bit. Negative numbers are
converted to an unsigned hex value via the two's complement notation, with the minimum
being -2147483648 or 0x800000000; numbers less than the minimum are converted to two's
complement with greater precision and also have the most significant digits discarded.
The return value is interpreted as a two's complement number with sign, so the return value is
an integer in the range -2147483648 to 2147483647.
Operands
expression : Number - A number.
Returns
Number - The result of the bitwise operation.
