CalcEx is an advanced calculator, in which you can type complex expressions and record your calculations as formulas for using them again later on. It is intended to ease up your personal calculations with a user friendly interface without having advanced features reduced. You can still use the full power of evaluation of complex expressions and usage of formulas, and it is still easy to understand and use. A useful calculator with many advanced options.
There are five fields that you can enter expressions. You can either have them calculated at once separately, or you can establish relations between them. These relations are simply established by having a calculated value in another field in the current one that you are typing your formula into. For example, you can use the value in the second field in your formula just by typing "E2" in your formula. For having the result of the first field in your calculation, you can type "E1" and for having the result of the third, type "E3" and for the fourth and fifth just type "E4" and "E5" respectively. As a numerical example, you can type three numbers into E1, E2 and E3 and have their mean value by typing "(E1+E2+E3)/3" to the fourth field.

One of these functions is the "formula library". By using this library, you can find many useful formulas, which can ease up your work and simplify your daily calculations. As a result, you get your operations speeded up. Also you can record the calculations you frequently make as custom formulas. This is the biggest advantage of the product; you can record the most frequently used formulas by you as formulas and then you can re-execute them with one click later on when you need them again.
