Text replacement - "[http://www.w3.org/TR/xpath-functions-30" to "[https://www.w3.org/TR/xpath-functions-31"
The math [[Module Library|XQuery Module]] defines functions to perform mathematical operations, such as {{Code|pi}}, {{Code|asin}} and {{Code|acos}}. Most functions are specified in the [httphttps://www.w3.org/TR/xpath-functions-3031/ Functions and Operators Specification] of the upcoming XQuery 3.0 Recommendation, and some additional ones have been added in this module.
=Conventions=
All functions in this module are assigned to the {{Code|<code><nowiki>http://www.w3.org/2005/xpath-functions/math}} </nowiki></code> namespace, which is statically bound to the {{Code|math}} prefix.<br/>
