bitwise operator &

[JeffB]

Will the code below work such that even_number is false if count is odd, true if count is even? Any issue with count actually being a floating point number instead of an integer? Seems not working in the field (count is always 0) but I don't have the hardware at hand to test.

global count
global even_number

count = 2;

if ((count & $1) == 0) even_number = 1 else even_number = 0

This works as you expect on my ARM CPU (FW vs 2.6.1.0).

 

Try adding “curly” braces:

if ((count & $1) == 0) {even_number = 1} else {even_number = 0}

 

Or multiline:

if ((count & $1) == 0) even_number = 1

else even_number = 0
