Calc is a Java calculator for MIDP or J2ME devices, such as a Java-enabled mobile phone or PDA. It was developed on a Sony Ericsson T610, which was my first Java-enabled phone but which has such a pitiful built-in calculator that I was compelled to develop this application. Calc works much like a good old HP calculator with RPN logic, but the stack has 16 elements and you can see many of the elements on the stack simultaneously. I have chosen to use RPN logic (Reverse Polish Notation), because operating it requires less keys, you need only ENTER instead of "(", ")" and "=". Additionally, being able to store and see intermediate results on the stack is very advantageous. Using the Real Java floating point library, Calc has 63 bits internal precision, which amounts to approximately 19 decimal digits accuracy, considerably more than normal calculators and computers. The exponent is 31 bits, which allows for numbers up to 4.197·10323228496. Handy when you want to calculate the factorial of 40000000
