Operation Functions(3.3)
- Jenni Wallin
The functions described in this section are used to perform operations on variables of the bitset type.
bitIsSet and bitIsCleared
The bitIsSet and bitIsCleared functions evaluate whether an individual bit is set or cleared. This can be done against either an integer, or a bitset value. For integer type, these are convenience functions that can be used instead of the regular logical operators.
boolean bitIsCleared ( int|bitset value, int bitnumber ) boolean bitIsSet ( int|bitset value, int bitnumber )
| Parameter | Description |
|---|---|
| Bitset or integer to evaluate |
| The bit to evaluate. 0 (zero) is the least significant bit, 31 is the most significant. |
Returns | false or true |
bsCreate
The bsCreate function creates an empty bitset.
bitset bsCreate()
| Parameter | Description |
|---|---|
Returns | An (empty) bitset |
bsSet and bsClear
The bsSet and bsClear functions set or clear a bit in a bitset.
void bsClear ( bitset bitset, int bitnumber ) void bsSet ( bitset bitset, int bitnumber )
| Parameter | Description |
|---|---|
| The bitset to modify |
| The bit to change. 0 (zero) is the least significant bit, 31 is the most significant. |
Returns | Nothing |
