Subject: RE: [xsl] Addition/Subtraction of numbers. From: Wendell Piez <wapiez@xxxxxxxxxxxxxxxx> Date: Wed, 23 Jan 2002 18:52:45 -0500 |
I have the understanding that the XPath number() function will return the string 'NaN' if the parameter passed in is not a number.
Though, at a lower level, won't the same function called twice with identical parameter(s) return the same thing?
So, when would your test of "number($t1) = number($t1)" fail?
Cheers, Wendell
