Need some testers for my prgm, try to find bugs
I have not made GUI as that will take awhile but I encourage you to use the prgm, please report bugs. All you need is python 2.0 or higher.

Please test on linux & unix if possible and feedback results
remember +1
there are 2 scripts, calc_2.1.0 for python 2.x and calc_3.1.0 for python 3.x
