On previous versions of PHP (5.4) works fine. This is a PHP BUG? Why the COM library affects the round function? Sorry for my bad english. Test script: --------------- <? round(0.00, 2); // Works $com = new COM("EpsonFPHostControlX.EpsonFPHostControl"); round(0, 2); // Works round('0', 2); // Works round(0.01, 2); // Works round(0.00, 2); // PHP crash round((float) 0, 2); // PHP crash ?> ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73332&edit=1
