My Calcul 1.0

My Calcul is your calculator and nobody elses: like most other calculator applications, it has a number of function buttons, which perform specific calculations on the number entered or calculated. But unlike in other applications, the buttons in My Calcul can be programmed by you to do exactly the calculations you want. You are free to set the name of each function button, the calculation formula behind it
Main features of My Calcul:
the calculation formulae can have up to 255 characters, with an unlimited number of parenthesis and named variables. The last value of each variable is memorized within one session, and it is offered as default value when the same variable is used again, in the same formula or in another formula.
the following functions are recognized in formulae: log, ln, factorial, sin, cos, tan, acos, asin, atan, cosh, sinh, acosh, asinh. The numbers pi and e are also recognized.
pages can be exported in text files, which can be edited outside the application (new functions, new pages,...) and re-imported in the application. Full pages can also be exchanged between phones, attached to an email or beamed via bluetooth...
the calculator can operate in standard algebraic mode or in RPN mode (Reverse Polish Notation).
the application is fully operational with the flip closed (P990i)
