Re: More-than-basic maths

just following up on this, in case anyone googles for info as i was doing.

- while the fxsl library works for simple tasks, it fails on more complex
operations when using saxon 8.3 (both fxsl-1.2 and fxsl for xsl 2).

- with xalan, fxsl-1.2 does work (so there seems to be a problem with
saxon), but, it turns out, xalan supports exslt (extended xsl) which gives
you access to math:... functions, which have a nicer syntax than fxsl (at
least, as far as i understood things).

so the simplest solution seems to be to use xalan with the exslt math
extensions.
