The _RESETBIT function is used to set a specified bit of a numerical value to 0 (OFF state).


Syntax

result = _RESETBIT(numericalVariable, numericalValue)


Parameters

  • numericalVariable is the variable to set the bit of and can be of the following types: _BYTE, INTEGER, LONG, or _INTEGER64.
  • Integer values can be signed or _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 has bits 0 to 7, INTEGER 0 to 15, and so on)


Availability

  • Version 1.4 and up.


Examples

Example 1:

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~%%
