Make a monitor with a variable named var, set it to 3.
Set the monitor's value and watch what it displays:

Code: Select all

128 & var  = 0
2^7 & var  = 3
2^7        = 128

I've run into similar issues trying to use bitwise operators.

After some investigation, I realized that the Lemur's bitwise operators '&' and '|' do not work on floating point numbers.

The solution is simple. Use the floor function to convert a floating point number to an integer before using bitwise operation.

Code: Select all

2^7 = 128.000
(2^7) & 3 = 3 <<< wrong answer because (2^7) is a floating point number in Lemur
floor(2^7) = 128
floor(2^7) & 3 = 0 <<< correct answer

Ah thanks for pointing that out! Makes sense, I guess it didn't register with me that I was getting a float out of it.

That said, exponentiation involving only ints ought to yield ints, so there's still a little bug here (whew).
