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~%% |
0 64 0 |
