p5-Math-SymbolicX-Error

Parser extension for dealing with numeric errors

This module adds numeric error (or uncertainty) support to the Math::Symbolic parser. It does so by extending the parser grammar of the Math::Symbolic module (that is, the one stored in $Math::Symbolic::Parser) with certain special functions that create constants as Number::WithError objects. (Math::Symbolic::Variable objects have been able to contain objects since the very beginning.)
