util.Integer.not

Returns the INTEGER value with all bits inverted.

Syntax

util.Integer.not(
  i INTEGER
 )
  RETURNS INTEGER

i is the integer value to convert.

Usage

The util.Integer.not() method inverts all bits of the integer values passed as parameter:

   i     :  210 (00000000 00000000 00000000 11010010)
-----------------------------------------------------
result   : -211 (11111111 11111111 11111111 00101101)

Note: Bitwise methods provided by the util.Integer class are based on the INTEGER type. Consider the following facts when using these methods:

The INTEGER type is a four-byte signed integer: If the bit at position 31 is set to 1, the corresponding INTEGER value will be negative. Thus, util.Integer.not(0) produces the INTEGER value -1 (11111111 11111111 11111111 11111111).
The NULL value for the INTEGER type is represented internally with the value 0x80000000 (10000000 00000000 00000000 00000000). When NULL is used with the util.Integer bitwise methods, it will be interpreted as 0x80000000 instead of a null value. However, if the result of the bitwise operation produces the value 0x80000000, it will be interpreted as NULL when used in an expression.

Example

IMPORT util
MAIN
    DISPLAY util.Integer.not(
            util.Integer.parseBinaryString("11111111111111111111111111111110") ) -- displays 1
END MAIN
