RE: Round value- Error

This mailing list is provided to allow the public to make comments on the
W3C XPath 1.0 specification, it is not an appropriate place to ask for
programming help.

A good place to ask XPath questions is the xsl-list at mulberrytech.com

The only suggestions I can make, given that XForms uses XPath 1.0, are:

(a) multiply by 100, call round(), then divide by 100.

(b) concat(substring-before(XXX, '.'), '.', substring(substring-after(XXX,
'.'), 1, 2))
