Well i don’t normally just clean it up, unless i want whole number, then i use ceil or floor. Normally i just do checking on the first two part of the float after the decimal, ie in your example, i would be comparing just 17.44 and ignoring the other stuff.

Where the top float is your calculation, the bottom float is your matching.
