And you could take that number and convert it to a float.
without loss.
There is a little with this approach. The float algorithm are generally
more efficient that the exact rational ones.
You don't get feedback about precision loss. So you never know whether
that efficient float computation was really faster.
Besides, I'm not sure that the float speedup will really matter for
SymPy in general. Do numeric calculations even take up a significant
fraction of SymPy's running times?
If no, we shouldn't care.
