Thinks it happens because we have used setLocale('da_DK'), because we i Denmark use , instead of . Why just use . everytime, as in other programming-languages ? Reproduce code: --------------- print ((float)'1.5').'<br>'; // Result 1,5 print ((float)'1,5').'<br>'; // Result 1 - Fine with me Expected result: ---------------- 1.5 1 Actual result: -------------- 1,5 1 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=26992&edit=1
