Notes
* Write formula using normal infix notation, for example (x^2+ y^2)/1.5. To execute statement use Evaluate command.
* Use variable to write generic formulas, by changing values assigned to the variables you wil be able to repeat calculation for all input data with minimal typing. Define your own functions which also can speedup your work and reduce probability of making an error.
* It is possible to write small functional programs using conditional ?: operator. For example sum of arithmetic progression can be calculated by the following function
sum(x)=x>0?x+sum(x-1):0
Calculator has only < and > comparison operators (because comparing floating point number for equality is any case bad idea). But it is also to check that value belongs to specified range using min<x>max operator.
* All statement you have entered and stored in database. You can select proper statement using List command. Statements are marked with three differen
