> The modulus fixes it for exact numbers.  It doesn't produce exactly the same result with floats, because of rounding.  Is that a problem?

I don't think that is a problem. The function uses a number of floating point operations producing inexact intermediate values. There is not an evidence that the proposed code produces more accurate value.
