functx:sort-as-numeric

Sorts a sequence of numeric values or nodes

Description

The functx:sort-as-numeric function sorts a sequence of numeric values or nodes. This is useful for untyped values, because the order by clause by default treats values as strings, and would therefore sort 100 before 99.
