[Lazarus] formatfloat negative zero (-0)

[Andrea Mauri]

Dear all,

using formatfloat function I got an unexpected behaviour.
If I round negative numbers I can get as result of formatfloat = '-0'.
I think it is a bug, since -0 has no meaning, zero is zero.
How can I make a workaround?
e.g.
label1.Caption:= FormatFloat('0.###', strtofloat(edit1.Text));
if in edit1.text I have -0.000001 I got -0 as result while I would like 
to get 0.

Is it a bug, what can I do?

Best regards,
Andrea Mauri
