This module adds big number support to Math::Symbolic. It does so by 
extending the parser of the Math::Symbolic module (that is, the one stored 
in $Math::Symbolic::Parser) with certain special functions that create 
arbitrary precision constants. (Math::Symbolic::Variable objects have been 
able to contain arbitrary precision objects since the very beginning.)
