【實用生產應用app】PG Calculator Free|最夯免費app-綠色工廠好玩App

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 numbersKey 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'; This is a free version of application. It display ads at the bottom of the screen.
