By floating point types I meant both float and double. So there would have to
be 2 specializations that call a common function. If specialization isn't
appropriate then I would suggest that always setting the precision would be an
appropriate solution. It certainly hurts performance, but lexical_cast isn't
the highest performance solution to start with.

My opinion is that lexical_cast should not require the user to control the
precision at the interface. It doesn't seem much like a "cast" when a
manipulator has to be applied.
No matter what, I think this needs to be fixed. Kevlin you out there?
