--- Comment #3 from Peter Jeremy <peterj at FreeBSD.org> ---
We could special case "y is a small positive integer" - that might give a
better result though it's unclear in this case.

Alternatively, we could look at what perl is doing - converting between ASCII
strings and floating point values is full of dragons and evaluating pow(10,i)
anywhere in that process suggests it's not being done optimally.
