Re: [xsl] Implicit casting from double to float

PS > However I can't actually verify that this should work in XSLT. I think it's clear that the intent is that it should work, it would be bizarre to allow automatic promotion from decimal to float (losing arbitrary amounts of precision) but not to allow promotion from double to float (losing a bounded amount of precision). Basically XPath works as if there is a numeric type from which decimal/double/float are all derived, and which if it existed would make many of these conversions much simpler to specify. However it wouldn't be the first time that there is a difference between what was intended to be specified and what the specification actually says...
