ANOTHER WAY TO SUPPORT MY WORK IS BY PURCHASING MY BOOK, CUSTOMER FIRST, VALUE NEXT.

THANK YOU FOR SUPPORTING MY WORK!

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: The square root √

Java/C# code

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

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

C++ code

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

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

Code result

[mXparser-v.5.2.1] Res: √2 = 1.4142135623730951

Case 2: The square root of the square root √√

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("√√16");

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

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("√√16");

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

Code result

[mXparser-v.5.2.1] Res: √√16 = 2.0

Case 3: The square root and parenthesis √()

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("√√(8+8)");

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

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("√√(8+8)");

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

Code result

[mXparser-v.5.2.1] Res: √√(8+8) = 2.0

Case 4: The roots of various orders ∜ ∛ √

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("∜16 + ∛27 + √16");

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

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("∜16 + ∛27 + √16");

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

Code result

[mXparser-v.5.2.1] Res: ∜16 + ∛27 + √16 = 9.0

Case 5: SIGMA summation operator ∑

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("∑(i, 1, 5, i^2)");

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

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("∑(i, 1, 5, i^2)");

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

Code result

[mXparser-v.5.2.1] Res: ∑(i, 1, 5, i^2) = 55.0

Case 6: Unicode name of a user defined argument

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Argument a = new Argument("α = 2π");
Argument b = new Argument("β = π/2");

Expression e = new Expression("sin(α) + cos(β)", a, b);

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

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ArgumentPtr a = new_Argument("α = 2π");
ArgumentPtr b = new_Argument("β = π/2");

ExpressionPtr e = new_Expression("sin(α) + cos(β)", a, b);

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

Code result

[mXparser-v.5.2.1] Res: sin(α) + cos(β) = 0.0

Case 7: Show all Unicode built-in keywords

Java/C# code
