Since round() returns an integer, and since (ignoring really
large integers, since I doubt you're concerned about them
here) floating point values can handle *integer* values
perfectly well, there's no reason it shouldn't do what you
The problem* with floating point is inaccurate representation
of certain _fractional_ values, not integer values.
