I would like to remove it, but before I would also like to know why you introduced it in the 1st place. The tests pass with or without changing the fp on almost each fp ops (sigh :). Can you explain why we need it and what tests are affected by this change please? Cheers, -- Pierre http://blog.thepimp.net | http://www.libgd.org
