The [_TOGGLEBIT](_TOGGLEBIT) function is used to toggle a specified bit of a numerical value.
|
|
|
|
## Syntax
|
|
|
|
> result = [_TOGGLEBIT](_TOGGLEBIT)(numericalVariable, numericalValue)
|
|
|
|
## Parameter(s)
|
|
|
|
* numericalVariable is the variable to toggle the bit of and can be of the following types: [_BYTE](_BYTE), [INTEGER](INTEGER), [LONG](LONG), or [_INTEGER64](_INTEGER64).
|
|
* Integer values can be signed or [_UNSIGNED](_UNSIGNED).
|
|
* numericalValue the number of the bit to be set.
|
|
|
|
## Description
|
|
|
|
* Can be used to manually manipulate individual bits of an integer value by toggling their state.
|
|
* A bit set to 1 is changed to 0 and a bit set to 0 is changed to 1.
|
|
* Bits start at 0 (so a [_BYTE](_BYTE) has bits 0 to 7, [INTEGER](INTEGER) 0 to 15, and so on)
|
|
|
|
## Availability
|
|
|
|
* Version 1.4 and up.
|
|
|
|
## Example(s)
|
|
|
|
*Example 1:*
|
|
|
|
```vb
|
|
|
|
A~%% = 0 '_UNSIGNED _BYTE
|
|
PRINT A~%%
|
|
A~%% = _TOGGLEBIT(A~%%,4) 'toggle the fourth bit of A~%%
|
|
PRINT A~%%
|
|
A~%% = _TOGGLEBIT(A~%%,4) 'toggle the fourth bit of A~%%
|
|
PRINT A~%%
