Advanced expressional variable Calculator - Variables, Expressions, Editable History of Expressions

This is an extremely Advanced and powerful Calculator. That is why it is named CalcAdva (Calculator Advanced). It is full of features:

1 The History function let you REVIEW AND RE-CALCULATE PREVIOUS CALCULATIONS. This is very useful, when you discover that a simple mistake has been done in a series of calculations.

2 The calculator is using Variables. You can DEFINE AND CALCULATE OWN VARIABLES , as well as using predefined variables. A special reserved variable named "result", always holds the result of your latest performed calculation.

3 There are predefined variables for all well known mathematical, physical and chemical constants. If you miss anything, you can of course add your own, or even change the predefined values of the existing variables.

4 The calculator works with EVALUATING EDITABLE FULL EXPRESSIONS , calculated after they are fully entered. For instance, when you enter 2*3+5, the first part (2*3) is not calculated when you enter the plus sign. Instead the whole calculation is done when you press the evaluation button (=). If you want to change or correct something in the expression, before pressing the evaluation button, just click in the window and edit it, just like any other Iphone text window.

5 CalcAdva has a SCIENTIFIC MODE. This looks and works like a normal scientific calculator, but with the extension of using expressions, and usage of variables, described above.

6 There is also the PROGRAMMER MODE. This mode is used for integer calculations, logical calculations (e.g. and/or operations) and bit operations (e.g. shift operations). In fact, you can enter any numeric expression valid for the C programming language, e.g. "!(a<<5)", assuming a is a defined variable.

Of course this application utilizes the full size of both the iPhone 5 and previous iPhone models.
