java bindings - how to bind a float to a jtable without getting -0.0 values?

Question

I have a JTable and I use binding (JTableBinding) to bind a list to it
In the object I use I have a getter and setter to each bind member.
This ofcourse is loaded with reflection.

My problem is that sometimes I get -0.0 instead of plain zero in the display. How can I format it to be alwayz 0 when it is -0.0? Thannks

Exactly. Didn't want to ask it in the comments and I thought it would assist to open new issue. — Bick, Jul 20 '11 at 09:07

I'm unfamiliar with JTableBinding, but a suitable implementation of TableCellRenderer may suffice. The relevant tutorial is here, and there's an example here.

add a special case to check if your float is 0 or -0 then print 0
