Hey all I finally figured out some bug in netpd that looked platform dependent. It turns out it actually is platform dependent. I do something that only creates rounding errors on Windows (or Wine), but not on Linux or macOS.
Attached patch illustrates the issue. It pre-calculates a look-up table. The resulting values in the table are slightly different between platforms. On Linux, I get only integer values between 0 and 255, while on Windows get some values like 8.99996 or 256. Assuming, that the code for [*~ ], [/~ ] and [phasor~ ] is the same on all platforms, I wonder where the difference is coming from. Is Windows simply less smart? Can this be fixed? Is there a cleaner way to do what I want? Roman
