Expected should be "0" here actually: (string) 0.3 -> converts to "0,299999999999999988897769753748434595763683319091796875". (float) "0,299999999999999988897769753748434595763683319091796875" -> converts to 0. I get the following output with both PHP 5.2.6: 0,299999999999999988897769753748434595763683319091796875 0,299999999999999988897769753748434595763683319091796875 0 0,3 Which is what I would expect. regards, Derick -- Derick Rethans http://derickrethans.nl | http://ezcomponents.org | http://xdebug.org -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
