Subject: [v][sf]printf additions (#, E, g, G)
From: php_lists@realplain.com ("Matt W")

Hi,

I've wished there was a *printf() float specifier that wouldn't include
trailing zeros/point, as simply converting to string (echo, %s, etc.) can
result in scientific notation, which I *don't* want (%g in
convert_to_string()).  The only other way that would result in what I want
is number_format() with my "no-extra-zeros option" patch. ;-)  So I was
originally looking for how to NOT pad %f to the specified precision, then I
thought why not add more of the stuff from C?  (And I see it's marked "not
done" in formatted_print.c.)

Can/should I go ahead and add support for the # flag/specifier, g/G, and E
(the missing compliment to e)?  Make everything work like C, except # used
with f/F, which would mean "remove trailing 0's/point" -- as C's behavior
with # and f (add point even when precision=0?) can be done in PHP.  (I
assume C's is for when precision is specified with * + parameter?)

Thoughts?


Thanks,
Matt
