      Built for use in my parser only.Serves to detect already and properly scanned numbers in the list where string models of other objects reside, e.g Variable objects,MOperator objects e.t.c It is a short cut method that allows for lightning number detection in an environment that contains numbers and other objects like variables, operators e.t.c as it does away with matching patterns and tests just a maximum of 2 numbers to know if the object is a number or not.
