That does look like a formatting bug.

It goes away if you use Normal on the series, but then one might not want to
do that.

Hi,

I have found (v. 5.0) an extrange thing: when one expands, e.g.,

Series[Sqrt[-1/2+x^2],{x,0,4}]

there appear a +- sign (which is correctly not present when one changes
-1/2 by -1)

is this a bug or a feature?

Thanks

L. Vergara
