THANK YOU!

The tutorial consists of more than 200 live examples from 50 sections given separately for JAVA, C# and C++. 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, C# (the code for C# is almost identical) and C++. To copy the code, double-click inside the frame.

Case 1: Binary number

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("b.10101 + B.10101");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("b.10101 + B.10101");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: b.10101 + B.10101 = 42.0

Case 2: Octal number

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("o.120 + O.120");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("o.120 + O.120");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: o.120 + O.120 = 160.0

Case 3: Hexadecimal number

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("h.2FE + H.2fE");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("h.2FE + H.2fE");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: h.2FE + H.2fE = 1532.0

Case 4: Unary number

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("b1.111 + B1.111");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("b1.111 + B1.111");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: b1.111 + B1.111 = 6.0

Case 5: Unary zero

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("b1. + 2");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("b1. + 2");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: b1. + 2 = 2.0

Case 6: Base 1 – 36 number literals

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("b1.1 + b2.101 + b3.102 + b8.71 + b10.12340 + b11.12340A + b16.FF + b25.fgh + b36.xYZ");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("b1.1 + b2.101 + b3.102 + b8.71 + b10.12340 + b11.12340A + b16.FF + b25.fgh + b36.xYZ");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: b1.1 + b2.101 + b3.102 + b8.71 + b10.12340 + b11.12340A + b16.FF + b25.fgh + b36.xYZ = 261308.0

Case 7: Base N numeral system

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("base(1, 1, 1, 1) + base(2, 1, 0, 1) + base(10, 1, 2, 3, 9) + base(16, 0, 1, 15) + base(50, 1, 2, 3, 49)");

mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("base(1, 1, 1, 1) + base(2, 1, 0, 1) + base(10, 1, 2, 3, 9) + base(16, 0, 1, 15) + base(50, 1, 2, 3, 49)");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());

Code result

[mXparser-v.5.2.1] Res: base(1, 1, 1, 1) + base(2, 1, 0, 1) + base(10, 1, 2, 3, 9) + base(16, 0, 1, 15) + base(50, 1, 2, 3, 49) = 131477.0
