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.

Arguments and Return Type

NameTypeDescription
$seq item()* the sequence to sort
return value item()*
