Problem: printf (& sprintf) dosn't handle exponential format for floats correctly
Comment: This isn't actually a bug since it isn't documented to work in the manual.
I nedded exponential format in my application and since the function
"formatted_print.c" already had some support for exp. format (but
not working correctly) the simplest solution was to fix it in the php
source code.
Below is my patch to "formatted_print.c" if you would like to include
it
in a future rease of PHP.
Thanks for a great tool for building web interfaces to databases !
