XPath in XQuery: Casting to xs:decimal

This works well for me

fn:sum($asset/(in:currentprice * in:quantity))

Open in new window


But I have tried to convert this to an xs:decimal as follows, but they do not work:

fn:sum($asset/(in:currentprice * in:quantity))/xs:decimal()

fn:sum($asset/(in:currentprice * in:quantity)/xs:decimal())

Open in new window


How can I cast the following XPath statement to xs:decimal ?

fn:sum($asset/(in:currentprice * in:quantity))

Open in new window


Thanks

If the casting to decimal is a precision issue,
you need to cast prior to the calculation in order to obtain correct results

fn:sum($asset/(in:currentprice/xs:decimal() * in:quantity/xs:decimal()))
