# bitwisenot

## bitwisenot() Function

Performs a bitwise 'not' operation of the {number}. A bitwise not is performed by taking the binary representation of the {number} and performing a logical 'not' operation on each of these bits.

Logical "not" Table

 Bit Result 0 1 1 0

Unfortunately its not quite as simple as the table above makes it appear since number are a string of 32 (or more bits) so a 1 in binary is actually a 00000000000000000000000000000001 and a 0 is actually a 00000000000000000000000000000000 so the table is now.

```       bnot of binary 00000000000000000000000000000000
is             11111111111111111111111111111111
which is -1 in decimal
```
```       bnot of binary 00000000000000000000000000000001
is             11111111111111111111111111111110
which is -2 in decimal
```
