Numis a lightweight floating point numeric class in num7/Num.java file for arbitrary precision results with always supreme precision.
Easy to use like school math and WITHOUT IEEE754 ISSUES or -0 FAILURES, it can be deployed
for web e-commerce developing, accounting apps and general math programs included financial ones.
Fairly portable to Python one (and vice-versa) also a jvm system can work with almost num7 capability.

To install
num7 packageenter the following:mkdir num7 //FROM YOUR OWN App.java BASE DIRECTORY CREATE num7 FOLDER cp Num.java num7 //PUT Num.java FILE INSIDE num7 FOLDER
