bit.test()
This function returns the Boolean value (
true
or
false
) of a bit at the specified index position.
Type TSP-Link accessible Affected by Where saved Default value
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
