The patch to fix this is here, along with all of the unit tests that had to be modified to take the new, correct behavior into account: http://pastebin.com/f641cf6fd Previous Comments: ------------------------------------------------------------------------ [2008-09-21 19:44:25] lbayuk at pobox dot com Description: ------------ PHP printf, sprintf, and fprintf with %e scientific notation produce a 1 digit exponent for values less than 1e10. Other implementation of functions by the same name produce a minimum of 2 digits in the exponent, as the C standard requires. Although it can be argued that PHP is not bound by other standards, the following comment in main/snprintf.c function php_conv_fp() [line 545] leads one to believe this is a PHP bug: /* * Make sure the exponent has at least 2 digits */ Reproduce code: --------------- <?php printf("%8.2e\n", 1000000); Expected result: ---------------- 1.00e+06 Actual result: -------------- <space>1.00e+6 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=46145&edit=1
