Math Functions
This module defines functions to perform mathematical operations, such as pi, asin and acos. All functions are described in detail in the XQuery Functions and Operators specification.
All functions are in the http://www.w3.org/2005/xpath-functions/math namespace, to which the math prefix is statically bound.
