{{DISPLAYTITLE:_TOGLEBIT}}
|
|
The [[_TOGGLEBIT]] function is used to toggle a specified bit of a numerical value.
|
|
|
|
|
|
{{PageSyntax}}
|
|
:{{Parameter|result}} = [[_TOGGLEBIT]]({{Parameter|numericalVariable}}, {{Parameter|numericalValue}})
|
|
|
|
|
|
{{Parameters}}
|
|
* {{Parameter|numericalVariable}} is the variable to toggle the bit of and can be of the following types: [[_BYTE]], [[INTEGER]], [[LONG]], or [[_INTEGER64]].
|
|
* Integer values can be signed or [[_UNSIGNED]].
|
|
* {{Parameter|numericalValue}} the number of the bit to be set.
|
|
|
|
|
|
{{PageDescription}}
|
|
* 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]] has bits 0 to 7, [[INTEGER]] 0 to 15, and so on)
|
|
|
|
==Availability==
|
|
* '''Version 1.4 and up'''.
