Passing a negative number, i.e. -1, into the format string "%0.2f" will give an invalid result, i.e. "-1.00[NULL]" where [NULL] is the 0th byte. Reproduce code: --------------- <? printf("%0.2f<br />", 1.51555); //ok printf("%0.2f<br />", -1.51555); //broken printf("%0.2f<br />", -1); //broken printf("%.2f<br />", -1.5); //ok printf("%.2f<br />", -1.51555); //ok printf("%0.2f<br />", 1.51555); //ok ?> Expected result: ---------------- I expect "-1.00" or appropriately rounded values with no trailing null bytes. Actual result: -------------- Cannot paste output, it is truncated at the first null byte. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=30764&edit=1
