ID: 31889 Updated by: tony2001@php.net Reported By: justinpatrin@php.net -Status: Open +Status: Closed Bug Type: Unknown/Other Function Operating System: Linux PHP Version: 4.3.10 New Comment: Fixed in snapshot -> closed. Previous Comments: ------------------------------------------------------------------------ [2005-02-09 00:04:40] justinpatrin@php.net Ok, you're right, my code is broken, I should have (float) instead of (int). Stupid me. And that fixes that code. However, consider this code: $str = '-.55'; $num = $num2 = 0; $num += $str; $num2 += (float)$str; echo $str."\n".(float)$str."\n".$num."\n".$num2."\n"; This outputs: -.55 -0.55 0 -0.55 But should output: -.55 -0.55 -0.55 -0.55 The snapshot fixes this, thanks. ------------------------------------------------------------------------ [2005-02-08 23:37:10] tony2001@php.net Please try using this CVS snapshot: http://snaps.php.net/php4-STABLE-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-STABLE-latest.zip ------------------------------------------------------------------------ [2005-02-08 23:35:11] helly@php.net Thank you for taking the time to write to us, but this is not a bug.
