ID: 24591 Updated by: [EMAIL PROTECTED] Reported By: arnarb at oddi dot is -Status: Verified +Status: Bogus Bug Type: Scripting Engine problem Operating System: Linux 2.4.18 PHP Version: 5.0.0b2-dev, 4.3.3RC2-dev New Comment:
Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is expected behaviour, consider what you are doing. You generate a sting containing "3,233" and then add 1 to it. PHP can only handle floats that use "." as a decimal point hence when the string is converted to a number it stops at the "," and 'rounds' the number to 3. Hence the result of 4 when 1 is added. To avoid this problem you should've performed the addition before printing the output.

This was addressed in bugs #17105, #17815 and others. Those reports were closed and the problem was claimed to be fixed in CVS as of November 2002 by iliaa and sniper. This bug is however still present in 4.3.2, as the reproduce code demonstrates. A quick look indicated that libc's strtod was being used for the conversion, I verified that it is working on my platform. Reproduce code: --------------- <?php printf("%.3f\n", 3.233); print sprintf("%.3f", 3.233)+1; print "\n"; setlocale(LC_ALL, "is_IS"); printf("%.3f\n", 3.233); print sprintf("%.3f", 3.233)+1; print "\n"; ?> Expected result: ---------------- 3.233 4.233 3,233 4,233 Actual result: -------------- 3.233 4.233 3,233 4 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24591&edit=1
