Subject: number() function
Author: Daniel Lucio

hi all!

I found that the XPATH function number() does not returns NaN when it receives a non numeric value! It returns '0'!
This happens as well with the round() function.
Does anybody knows a workaround for this?? I need to test whether a value is numeric!

Regards!

What Stylus Studio version are you running? This problem was fixed a lot of
time ago; can you try upgrading to 3.1 BL69f?

Hi!

I was using Excelon 3.1, build 069e. I just downloaded the latest version (069f) and it keeps doing the same!
This is the behavior of excelon's built in processor:

function spec excelon

number(12.3) 12.3 12.3
number("12.3") 12.3 12.3
number("abc") NaN '0' <-WRONG
number(NaN) NaN NaN

Regards!

I can see that now. We are working on that; the fix will be available shortly.

Thanks,

A last comment on this. I just used Xalan-J, and the following piece of code works correctly:

just a test!

What you mean here? I'm not sure I'm following you.

Sorry, I tried to put some example XSLT script but your server erased those lines.
What I am trying to say, is that Excelon's internal processor does not returns 'NaN' from an instruction like number("abc") (behavior that I need to test if a value is numeric!). But Xalan-J does! So, the same XSLT script runs correctly using Xalan-J but not with Excelon's internal XSLT processor.

Regards!

Yes, I understood that (and we have already fixed the problem); I was
trying to understand the message in which you say:

Upss, something happened with the XSLT code in HTML mode!!
{xsl:if test="string(number(.))='NaN'"}
{xsl:message}just a test!{/xsl:message}
{/xsl:if}

What do you mean?
