So, I'm trying to evalutate the percent value my current health is of my max health. Both my health and max health are provided by the game as integers, and without decimal values.

@health is 2723
@maxhealth is 2966

when I do %float(@health/@maxhealth), it returns 0, where it seems like it should return 0.918071476736345

If from the command line I do #show %float(2723/2966) it returns 0.
If I do #show %float(2723.0/2966.0) it returns 0.918071476736345.

How do I convince %float to behave correctly on inputs that aren't already float values? Alternatively, how do I convince my integer variables to prentend they're float variables for the duration of one evaluation?

EDIT:
So, I went to each of the involved variables and manually set them to the Float type, and this seems to have fixed it.

Yes, you have to set at least one of the operands to floating-point type for the expression to evaluate as a floating-point result. You were only converting the number to floating-point after it already did the integer division. It's a common mistake, especially among non-programmer types, because your calculator will just automatically convert them for you (and that's because the calculator assumes all numbers are floating-point).

To make it even clearer you need to do something like this. #show (%float(@health)/%float(@maxhealth))
