This is a basic adding machine written in C dialect and works under DOS brief. The number cruncher performs all the essential arithematic operations including expansion, subtraction, trignometric figurings, and numerous different capacities. It can likewise ascertain logrithms, powers, and foundations of whole number numbers.
