UPDATED 24 FEB 2015

Minor bug fixes:

KNOWN ISSUES: 2 March 2015

1. Some functions cause the FFSE button to be relabelled DFSE. This a legacy of an earlier version, it does not affect the operation.

2. PGM and the programmed functions set the calculator to a standard configuration and resets after the operation. This means that all trig functions are in degrees. This is the correct operation but can cause confusion if the user is operating in Radians or Grads and is unaware of this limitation.

I will endevour to make this operation clearer to the user in the next update.

3. The conversion of negative numbers from one radix to another is not correct. Update coming.

IN THE PIPELINE:

Suggestions welcome.

## PG Calculator (Free)

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 ?

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

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;

* Exponentiation and the calculation of square roots;

* Basic and inverse trigonometric functions;

* The natural logarithms and the decimal;

* Calculator allows you to enter numbers in decimal, binary, octal and hexadecimal;

* Calculator offers the possibility to change the appearance of the user interface with built-in 'skins';

NOTE: This version of the application is free. It displays ads but has the same functionality as the 'PG Calculator (Standard)' edition.

A simple calculator, the display of which indicates expressions and gives easy operation for editing.

The calculator PanecalST includes features below:

*Four arithmetic operations, root, percentages, and tax calculations

*Calculations with parentheses

* Memory, M+, M-, MR, MC

*Scroll up/down lines

*Easy editing by using a cursor operation

* Cut, copy, and paste

*Expressions history and answer history

*Configurable grouping separator and decimal point

Four arithmetic operations:

1 + 2 - 3 × 4 ÷ 5 = 0.6

Root:

√( 2 × 2 ) = 2

Percentages:

500 + 20% = 600

500 - 20% = 400

500 × 20% = 100

100 ÷ 500% = 20

Tax calculation:

500 Tax+= 525

525 Tax-= 500

Parentheses:

( 1 + 2 ) × ( 3 + 4 ) = 21

( 1 + 2 ) ( 3 + 4 ) ( 5 + 6 ) = 231

Grouping separator and decimal point:

123,456,789.1 + 0.02 = 123,456,789.12

123.456.789,1 + 0,02 = 123.456.789,12
