THANK YOU!

The tutorial consists of more than 200 live examples from 50 sections. Each of the examples can be copied and run on your own environment. In addition, mXparser provides an extensive collection of over 500 built-in math functions, expressions and symbols. Familiarize yourself with the scope and the syntax. Live testing is the best way to learn. Good luck! 🙂

Below is the code for JAVA, the code for C# is almost identical. To copy the code, double-click inside the frame.

Case 1: Units of length / distance

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("( 95*[cm] + 200*[m] + 1*[km] ) / [km]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: ( 95*[cm] + 200*[m] + 1*[km] ) / [km] = 1.20095

Case 2: Units of time

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("( 60*[min] + 2*[h] ) / [h]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: ( 60*[min] + 2*[h] ) / [h] = 3.0

Case 3: Units of information

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("8*[Mb] / [MB]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: 8*[Mb] / [MB] = 1.0

Case 4: Units of volume

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2000*[l] / [m3]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.0.0] Res: 2000*[l] / [m3] = 2.0

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("2000*[l] / [m3]");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
[mXparser-v.5.2.1] Res: 2000*[l] / [m3] = 2.0

Case 5: Express 4 feet in inches

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("4[ft]/[inch]");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.2.1] 4[ft]/[inch] = 48.0

Case 6: Express in square kilometers the area of a rectangle measuring 100 meters by 2 kilometers

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("100[m] * 2[km] / [km2]");
mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.2.1] 100[m] * 2[km] / [km2] = 0.2

Case 7: List of supported units

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
mXparser.consolePrintHelp("type=unit");
