* Hyperbolic functions;
* natural and decimal logarithms;
* factorials;
* conversion between binary, octal, hexadecimal, decimal and scientific (exponential) number formats;

There is a library of common mathematical and physical constants which can be used in calculations in both RPN and Algebraic modes.

PG Calculator Pro allows to use user-defined variables.

PG Calculator Pro has built-in Time Value of Money solver and IP Subnets Calculator.

The user interface of the calculator can be changed by using various skins supplied with the application.

PG Calculator is an application that turns your smartphone or tablet into a powerful scientific calculator with nice and simple user interface.

PG Calculator offers two operational modes: algebraic and RPN:
* In algebraic mode you can enter the entire math expressions such as (2+3)*(4-1) or sin(Pi/3)+cos(Pi/6). It then gives you the correct result according to the conventional mathematical operators.
* In RPN (Reverse Polish Notation) mode you first input your numbers and then tell calculator what to do with them. So for example if you want to calculate (3+4)*5 you simply type as follows: 3 ENTER 4 ENTER + 5 ENTER *. The ENTER key places the number on stack and the operator keys do the task on the numbers

Key features:
* Two operational modes: algebraic and RPN;
* Basic mathematical operations such as addition, subtraction, multiplication and division;
