PHP Bug Type: Unknown/Other Function
Bug description: printf %e format should make 2 digit exponent
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
