My Calcul is your calculator and nobody else’s: 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 and the calculation formula behind it.
The calculation formula behind each button can take several named  variables and an unlimited number of parenthesis. In the case of  function ft-in>cm, the formula has 2 variables named inches and  feet?:
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.
* the calculator can operate in standard algebraic mode or in RPN mode (Reverse Polish Notation).
