## 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 decimalIf you are unsure why the results are negative then you can get more information by reading Twos_complement

### Usage

```
[h: val = bnot(num)]
[h: val = bitwisenot(num)]
```

### Examples

`[bnot(1)]`

Returns 0.
