Purpose
Function to perform bitwise NOT operation
Syntax
BITNOT(<expN>)
See Also
BITAND(), BITCLEAR(), BITLSHIFT(), BITOR(), BITRSHIFT(), BITSET(), BITTEST(), BITXOR()
Description
The BITNOT() function performs a bitwise NOT operation on the specified numeric parameter. If <expN> is not an integer, it will be converted to an integer value before the operation takes place.
BITNOT() switches each bit in turn of <expN1>. Each 1 becomes a 0, and each 0 becomes a 1.
| <expN> bit | Result bit |
|---|---|
| 0 | 1 |
| 1 | 0 |
Example
x = 3 && 00011 ? bitnot(x) -4 && 11100
