Fixed point to floating point
WebJul 17, 2024 · Try increasing the word length in the Settings section of the fixed point tool, allowing more room for calculation and hence avoiding overflows. Thanks. No. Float system gives perfect output. Fixed point model gives output zero. As I said earlier, I wanted to know the method of troubleshooting the problem.
