_SETBIT - QB64Official/qb64 GitHub Wiki
The _SETBIT function is used to set a specified bit of a numerical value to 1 (on state).
Syntax
result = _SETBIT(numericalVariable, numericalValue)
Parameter(s)
- 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 1 (on state).
- Setting a bit that is already set to 1 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.
Example(s)
A~%% = 0 '_UNSIGNED _BYTE
PRINT A~%%
A~%% = _SETBIT(A~%%,6) 'set the seventh bit of A~%%
PRINT A~%%
