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

Details
This function returns
result
, which is the result of toggling the bit
index
in
value
.
Any fractional part of
value
is truncated to make it an integer. The returned value is also an integer.
The least significant bit of
value
is at
index
position 1; the most significant bit is at
index
position 32.
The indexed bit for
value
is toggled from 0 to 1, or 1 to 0.
Example
testResult = bit.toggle(10, 3)
print(testResult)
The binary equivalent of decimal 10 is 1010.
Toggling the bit at
index
position 3 returns a
decimal value of 14 (binary 1110).
Output:
1.01
