I was just looking at this bit of code the other day. Do you have the
allow-general-expressions extension enabled?

It sounds like a bug to me, if you can reproduce it with a small test
case and post it in the issue tracker

  https://github.com/ndw/xmlcalabash1/issues

I'll fix it asap.

It's not on purpose. :-)

If you're using the general expressions extension, try casting explicitly
to xs:decimal yourself:

  <p:with-param name="scale" select="xs:decimal($scale)">...

If not, then I'm even more confused.

                                        Be seeing you,
