Map Function

This function allows to convert a value from one range to another range:
  • input x with range bounds xmin and xmax
  • output y with range bounds ymin and ymax

The function is especially useful for analog inputs.

The formula is

I've added checks on the output, so the returned value can't exceed the range bounds ymin and ymax.

Inputs and output are integers, but internal calculations are done with floatings.

Once again, avoiding the spaghetti syndrome was impossible!
