Format string decimal point problem


I am trying to apply the following easy-to-state formatting rule to
display a number:

- If the number is positive or negative, display it in the 'default'
way
- If the number is zero, the output should be an empty string

Now I know this is trivial to code, but the elegant solution would be
passing a custom format string to ToString(). The problem is, I can't
make one that works: There doesn't seem to be a way to combine the
'pre-defined' numeric formats with the user-defined format idea of
semi-colon-delimited differing formats for positive;negati ve;zero
inputs.

I tried "#########.#### ##;-######.#####;" which *almost* works, except
that for whole-number inputs it still displays a decimal point. There
doesn't seem to be a 'conditional decimal point' formatting character
in the same way that # is a 'conditional digit' formatting character.

As I said, this isn't desperately important, but I would be interested
to learn if I am missing something.

Larry,

You mean that you make work from
\\\
a = ""
if b <> 0 then a = b.tostring
///

I never take the time to think about those things to much

I check the characters I have to type for that mostly to see what I take.

:-)

That doesn't insert the thousand seperators he wants AFAIK

Rinze,

Are you sure is there not a default toString format what you can set in the
language-culture settings.

Oh I see Fries is not a culture.

Luckily I'm not from Friesland, only my name is :P

Anyhow, I haven't played around with the culture settings that's why I
added the AFAIK (As Far As I Know). I guess I'll have to look into that.

I'm a stupid ASP programmer and I dont do Javascript (except for very simple tasks anyway), and I'm in a bit of a predicament. I've used a javascript table sorting script from here: http://www.ipwebdesign.net/kaelisSpace/useful_tableSort.html This works great except it doesn't sort my UK formatted dates properly, and I end up with something like this: Birth Date (dd/mm/yyyy)
