Thank you for your contribution Michael and Paul.
I share your opinion about the http://www.exslt.org/ mathematical module.
It may be integrated in the XQuery language since the modules
will be fully specified by the Working Group. I will use it in our implementation
( http://www.gael.fr/drb and http://www.gael.fr/derby )
until next releases of the Working Draft.
 
Best regards

A standard library of mathematical functions suitable for use in XPath, and therefore in XQuery, has been defined at http://www.exslt.org/. These are gradually being adopted by XSLT vendors, and if there is user demand, I see no reason why XQuery vendors should not implement the same functions.

Subject: Mathematical functions
Hello,
 
is it possible to use mathematical functions in XQuery using a standardised library with a dedicated namespace ?
If not, what is the best way to use functions not defined in the built-in functions core library without defining them
into the XQuery itself ? Defining sin or tan using Taylor series may be very inefficient.
 
Best regards.
Stephane.
