Re: [xsl] ceiling(), floor(), and data types

Fully supporting xs:integer or xs:decimal would need for implementers to support arithmetics with infinite precision while, usually, programming language just allow int, long,..., float, double (even just double for _javascript_, actually, while COBOL is smarter!).

Then, specifically for ceiling() or floor(), if the parameter is a huge double with precision > 10, those cannot return better than the parameter itself as a double, don't you think?

Dear XSL List,

I was surprised to learn today that ceiling() and floor() do not obligatorily return a value of type xs:integer. If I've understood correctly that they necessarily return a value that a human would consider an integer, is there a reason that other return types are permitted?

Thanks,

David
