how to force decimals to display in exponential notation

[revansx]

Hi folks,

I am programming a page that displays scientific data retrieved from a
data source to an asp-web page and i would like to force all number to
be formatted/displayed in scientific notation no matter what the value
is. (i.e. x = 123 would be displayed as x = 1.23e+02). The standard
function "formatnumeric(x[,n])" does not seem to be able to do this for
me or at least I don't know how to use it that way.

Can anyone show mw a way?

thanks!

Hi Dave,

Thanks for the quick reply.

Isn't JScript a client-side scripting language?
I really need to be able to do this on the server-side.
....or did I misunderstand your solution?

Hi Dave,

No. JScript is a scripting language.
ASP support several scripting languages, including vbscript and jscript,
as well as others. See this for tips:
http://www.aspfaq.com/show.asp?id=2045

It is really incorrect to use "javascript" interchangeably with
"client-side script". IE supports the use of both vbscript and jscript
in client-side script. Other browsers only support javascript ... hence
the propensity for using the terms interchangeable.

I really need to be able to do this on the server-side.
...or did I misunderstand your solution?

Yes. He intended you to implement it in a server-side script block.

JScript is availabel as a scripting language in ASP. I use it exclusively.

Now, I am not saying you need to change languages (though I think the
benefits of using JScript for ASP are many). ASP actually allows you to use
both languages in the same script. There are some rules to keep in mind,
however.

To begin with, understand that there are three distinctly different types of
scripting blocks:

1. <script runat="server" language="jscript"> ... </script>
2. <script runat="server" language="vbscript"> ... </script>
3. <% ... %>

I will refer to #3 as "inline" from here on.

When the script is parsed, the parser determines the language for inline
scripting, then executes the blocks in the following order: 1-3-2 (if inline
language is VBScript), or 2-3-1 (if JScript). HOWEVER, any block can call a
function from any other block. It does not matter what order the blocks
appear within the script.

If you want to mix-and-match languages, then, it is a good practice to
encapsulate the cross-language bits in functions:

<%@Language=VBScript%><%

Randomize
Dim N : N = 100 * Rnd()
Response.Write(FormatEXP(N,10))

%>
<script runat="server" language="jscript">
function FormatEXP(n,d) {
return n.toExponential(d)
}
</script>
