Function No
Usage
result = bit.test(value, index)
result
Result of the bit manipulation
value
Specified number
index
One-based bit position within value to test (1 to 32)
Details
This function returns result, which is the result of the tested bit.
The least significant bit of value is at index position 1; the most significant bit is at index position 32.
If the indexed bit for value is 0, result is false. If the bit of value at index is 1, the returned value is true.
If index is bigger than the number of bits in value, the result is false.
Example
testResult = bit.test(10, 4)
print(testResult)
The binary equivalent of decimal 10 is 1010.
Testing the bit at index position 4 returns a
Boolean value of true.
Output: true
