Hi,
Not sure what you are really asking. Are you trying to create a float type variable, load it with a value and use it in an equation? Are you getting errors when you do this?
Here is a short snipped of code using a float. Let us know if you are asking something different.
Code:
float number = 2.314;
float answer;
answer = number * 1.5;
