digitalmars.D.learn - ignored phobos request

reply "Saaa" <empty needmail.com> writes:
Some time ago I requested something on .D, but it was ignored.
I'm interested in why this is so.
It was only a small request, maybe not fitting for .D but dsourse/phobos 
said that was the place for such things.
(Maybe it was unintelligible again?)

Could an option be added to the formatting to elide trailing zero's for %f ?
That way it is possible to create an more optimal formatting for which the
following holds:

float f;
s = format(f);
float f2 = to!(float)(s);
assert(f==f2);

The formatting I'm trying to get can be seen here (decimal):
http://www.h-schmidt.net/FloatApplet/IEEE754.html
try 0.1, 0.0001, 10 & 10000000

%g fails to format like this because it uses %f for as small as 10^-5,
thus loosing precision for floats with leading zero's, like 0.0001234567

It would be even nicer to have this kind of formatting added to std.format!
---

With little effort the default float format even could be lossless, wouldn't 
that be nice?

The place (.D) was right, but I think your timing was bad. :) You posted 
it in the middle of the (very heated) properties debate, and people were 
way too preoccupied with that to care about other things.

You could try the newsgroup again if you feel it is something that needs 
discussion, or you could simply post an enhancement request in Bugzilla:

I think it's a good idea. :)

I always thought bugzilla was only for bugs..

Nope, enhancement requests go in there too. :) Make sure to select 
"enhancement" in the "severity" dropdown list.

IIRC when it was set up there was a bit of debate about that and items in 
it got changed from "bugs" to "issues" to denote that distinction.
