UIBuilder math borked?

[Drumstix42]

This only started happening to me recently and I don't know why.

Doing any sort of math in the UIBuilder with variables is resulting in values like:
1e+002.

I really don't understand why. It wasn't doing it before. I tried re-extracting UIBuilder freshly, and no difference.

I can add numbers like var=5+5
But as soon as I do Element.width+5 I get the weird number results....

I tried wrapping things in Int() with no difference in result.
It makes testing positioning code in UIBuilder impossible


Any ideas?
