Assam-Calcu: A Programmable All-Purpose Calculator 2.5

Assam-Calcu is a 12-digit multi-purpose calculator that can store and recall millions of your old calculations - whether ordinary or scientific. It may also be easily programmed to run hundreds of calculation-steps in one go. It is designed to be equally convenient for purposes as varied as the simplest grocery arithmetic as well as the most advanced technological computations.

The basic operation in Assam-Calcu is execution of a simple command-line (say, `Answer = 673+245`), of which the left side is a variable (say, `Answer`), and on the right side of which lies an expression (say `55*4` or `Mass*(3.0E8)**2`). If the right side uses one or more variable(s), e.g., `Mass`, their values must have been defined in earlier steps. Compared to most calculator-instruments, Assam-Calcu offers the much wider range of 9.9E+300 to 1.0E-300 for its results. It also contains a database of values for popular constants & conversion-factors. v2.5 simplifies the UI and offers weekly backup reminders.
