Sorry, but we have to reject this request. thanks for your understanding, ------------------------------------------------------------------------ [2009-03-24 15:03:53] peter at lvp-media dot com Hereby a simple bug47752.phpt file. Tested it on a patched- an an unpatched installation, results as expected. Strictly speaking +0 and -0 are valid integers, even though neither of them is positive or negative.
