Comment(by maeder):
I suppose arithmetic on these non-normalised rationals does also not
behave like on doubles (IEEE).
I would expect toRational to fail on NaN and Infinity and to convert -0 to
0.
But rather than introducing a multi-parameter type class I would just add
non-overloaded plain conversion functions between Float, Double, CDouble,
etc.
