public static NumericValue power(NumericValue n, NumericValue e) throws XPathException
If e is a non-negative integer, then the result will have the same type as n, except that a float is always promoted to double.
If e is a negative integer, then the result will have the same type as n except that a float is treated as a double and an integer is treated as a decimal.
If e is not an integer (or an xs:decimal representing an integer), the result will be a double.

XPathException
- if an arithmetic overflow is detected. However, there is no guarantee that
overflow will always be detected, it may (especially with double arithmetic) lead to wrong answers
being returned.public static double constant(XPathContext context, String name, double precision) throws XPathException
