Declaration of a variable

[agompert]

I know I just need to experiment a little, but, I was wondering what type of a variable to declare. All I’m doing is just counting wheel turns on a wheel and multiplying it times the distance around the wheel. My counter counting wheel turns, is a 16 bit binary number. I want to multiply it by a number like 3.1 or 1.8 etc. to give me total feet or what ever. The new variable, feet, which I will display on a LCD, would this variable be a float, to give or show the decimal point? Or would it be an Int16 or a long variable? A float number, to my understanding, is 32 bit, which is way overkill for what I’m doing. All I need is the 16 bit binary value would
be enough. But to show a decimal point, it would be a float variable.
right?

In a sense, it is 'up to you'. However float operations, will always be _slow_. One possibility (if the sizes are suitable), is to use the 'scaled integer' ability of CCS (the %w output specifier in printf).
In the examples given, you would start with the int16, and instead of multiplying by 3.1, or 1.8, multiply by the value *10.
So:
