Unicode math | mXparser – Math Expressions Parser for JAVA, C#, C++, Kotlin, Android, .NET/MONO/Xamarin – Mathematical Formula Parser

TO SUPPORT MY WORK, ORDER A COMMERCIAL LICENSE 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! πŸ™‚

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)");

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

// ...
ExpressionPtr e = new_Expression("∜16 + βˆ›27 + √16");

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());
Code result 
[mXparser-v.5.2.1] Res: ∜16 + βˆ›27 + √16 = 9.0
Case 5: SIGMA summation operator βˆ‘ Java/C# code 
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("βˆ‘(i, 1, 5, i^2)");

Code result 
[mXparser-v.5.2.1] Res: βˆ‘(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("Ξ± = 2Ο€");
Argument b = new Argument("Ξ² = Ο€/2");

Expression e = new Expression("sin(Ξ±) + cos(Ξ²)", a, b);

ExpressionPtr e = new_Expression("sin(Ξ±) + cos(Ξ²)", a, b);

mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate());
Code result 
[mXparser-v.5.2.1] Res: sin(Ξ±) + cos(Ξ²) = 0.0
Case 7: Show all Unicode built-in keywords Java/C# code 
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
mXparser.consolePrintHelp("unicode");
