* If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en.wikipedia.org/wiki/Kibibyte.

* If you can't find HEX, BIN or OCT modes, go to Menu > Settings and make sure that 'Radix Modes' is enabled.

* If the percent key appears to give wrong answers, make sure you are pressing '=' at the end, e.g. '25 + 10 % =' will give 27.5.

* If sin/cos/tan functions don't give the answer you are expecting, make sure you are in the correct angle mode. Degrees, radians and grads are supported, indicated by DEG, RAD, GRAD in the display. Use the DRG key to change mode.

* If any of the digit keys are disabled, or the decimal point doesn't work, or you have answers with letters in, or basic arithmetic appears to be wrong, then you are in binary, octal or hexadecimal mode. Press DEC to return to decimal operation. If you don't need these modes, please make sure that 'Radix Modes' is disabled in the settings.

## PG Calculator (Pro)

Do you need a simple calculator which allows you to do basic mathematical operations? Or perhaps you are more demanding user and need to calculate trigonometric functions or logarithms ?

Do you prefer to calculate complete algebraic expressions... or maybe you are a fan of Reverse Polish Notation (RPN) ?

Would you like to have a calculator which looks like 'real' on the screen of your smartphone or tablet?

All of this and much more is offered by PG Calculator Pro - the only calculator you will ever need.

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

PG Calculator Pro 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;

* Exponentiation and the calculation of square roots;

* Basic and inverse trigonometric functions;

* The natural logarithms and the decimal;

* All mathematical operations and scientific functions can work with complex numbers

* You can input numbers in decimal, binary, octal and hexadecimal;

* You can change the appearance of the user interface with built-in 'skins';

There is a library of common mathematical and physical constants which can be used in calculations in both RPN and Algebraic modes. You can also use user-defined variables in your computations.

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