# Scientific Calculator Plus

#### + By CYZ SOFT

Scientific Calculator Plus (Chinese: 可编程科学计算器) is a powerful mathematical tool for Android, Windows, MacOSX, Linux and Java platforms to do mathematical analysis and evaluate complicated mathematical expressions similar to Matlab. More than Matlab, it has a mathematical equation(s) solver which helps user to solve mathematical problems. It supports 1. complex number, 2. array (matrix), 3. (higher level) integration, 4. chart plotting, 5. string, 6. programming (using a language similar to Basic and Matlab) and 7. unit conversion besides the basic calculations. It can run in both Android phones and tablets, PC and MAC. Scientific Calculator Plus for Android includes a Scientific Calculator Plus for PC and Mac.

This calculator has provided more than 100 diffused mathematical functions covering trigonometric calculation, complex number, matrix, integration, string and chart plotting. It is also able to handle mathematical operators like plus, division, power, percent, etc. And these operators fully support matrix and complex numbers. In this way user is able to evaluate complicated expressions, which are either not supported or hard to input in most traditional calculators. Moreover, the calculator is actually a user interface of an easy-to-use programming language called MFP. As such, users can develop their own functions using this tool by a PC editor, store them in mobile SD-card and use them in calculator or command line. As a programmable tool, it can do everything.

The calculator is also able to think for user. It is able to solve unknown variables from complicated expressions and show the result to user. To calculate result of an expression, user input an expression like 3 + log(4.1 / avg(1,5,-3)). To solve unknown variables, user input single expression like log(x) - 7== 3, or a group of expressions like
y1/3+y2==7
y2/2-y3+y1==9
y3+y1+y2==2.4
. Then simply press start button, user will see value of 3 + log(4.1 / avg(1,5,-3)) or solved x or y1, y2 and y3 value.

This calculator has two basic user interfaces: smart calculator interface and command line interface. In the smart calculator interface, user is able to define variables, solve equation(s) and input expression(s) from historical records, using keyboard or clicking function buttons. Function buttons are configurable so that user is able to define his/her input keypads to type in user-defined functions quickly.

In the command-line interface (which works like Matlab), user uses keyboard to input expressions and sees the print output (which is not shown in the calculator interface) and return value. Command-line interface is best tool for developers to output intermediate results in their functions.

In order to help user input and evaluate (higher level) integration and plot 2D charts, this calculator includes built-in integration and chart-plotting utilities. User no longer needs to type long and complicated expressions. Instead, by simply filling the text fields and pressing buttons, user will see the results or the charts. All the charts are automatically saved in SD-card which can be viewed and managed by file manager of the calculator later on.

Like Matlab, the calculator also provides a small program editor which gives developers much convenience to build their own functions. Nevertheless, they can also user a PC editor to do this job and save the program files in SD-card for future use.

To help user use Scientific Calculator Plus in mobile devices and different computers, Scientific Calculator Plus for Android also includes a Java based Scientific Calculator Plus for any Windows / MacOSX / Linux machine which has installed Java (v. 1.6 or above). User can connect mobile device to any PC or MAC via a USB cable, launch the JMathCmd.jar in SDcard\AnMath\ folder on Windows / MacOSX / Linux and develop MFP programs using PC or MAC, then run the programs in mobile device later on.

## Recently changed in this version:

* Show singular point(s) in chart, i.e. hyperbolic curve and y == tan(x) can now be correctly plotted. Note that user must set step to auto to enable this function;
* Add if function (which is similar to but more powerful than the if function in Excel) so that user can use a one line statement to construct an if block;
* Several bugs fixed;

It is Nice to have.... Somthing new & got everything I need... Thanks.

• (72 stars)

Well done

• (72 stars)

The inputpad config tool is very useful to me, I can develop my functions and input them with only one click. And the math equation solver is good too.
