The [_RESETBIT](_RESETBIT) function is used to set a specified bit of a numerical value to 0 (OFF state).
|
|
|
|
## Syntax
|
|
|
|
> result = [_RESETBIT](_RESETBIT)(numericalVariable, numericalValue)
|
|
|
|
## Parameter(s)
|
|
|
|
* numericalVariable is the variable to set 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 setting them to 0 (OFF state).
|
|
* Resetting a bit that is already set to 0 will have no effect.
|
|
* 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)
|
|
|
|
```vb
|
|
|
|
A~%% = 0 '_UNSIGNED _BYTE
|
|
PRINT A~%%
|
|
A~%% = _SETBIT(A~%%,6) 'set the seventh bit of A~%%
|
|
PRINT A~%%
|
|
A~%% = _RESETBIT(A~%%,6) 'Reset the seventh bit of A~%%
|
|
PRINT A~%%
|
|
|
|
```
