I want to calculate the duration of a loop and use this value in my code. Hovewer the result (I called 'timeloop") gived me often 0 because the code is short, so I would like to constrain this value with minimum 1 with the code : timeloop = max(millis() - timeprev , 1); But in this example below, …

I don't understand this bug
