bitAnd()
Usage
bitAnd(integer1, integer2)
Description
Function (Lingo only); converts the two specified integers to 32-bit binary numbers and returns a
binary number whose digits are 1’s in the positions where both numbers had a 1, and 0’s in every
other position. The result is the new binary number, which Lingo displays as a base 10 integer.
In JavaScript syntax, use the bitwise operator "
&".
Parameters
integer1
Required. The first integer.
integer2 Required. The second integer.
Example
This statement compares the binary versions of the integers 6 and 7 and returns the result as an
integer:
put bitAnd(6, 7)
-- 6
