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: Bitwise unary complement

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e1 = new Expression("@~ 2");
Expression e2 = new Expression("@~ b.10");
double v1 = e1.calculate();
double v2 = e2.calculate();
mXparser.consolePrintln("Res 1: " + e1.getExpressionString() + " = " + v1 );
mXparser.consolePrintln("Res 2: " + e2.getExpressionString() + " = " + v2 + ", bits = " + mXparser.convDecimal2OthBase(v2, 2));

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e1 = new_Expression("@~ 2");
ExpressionPtr e2 = new_Expression("@~ b.10");
double v1 = e1->calculate();
double v2 = e2->calculate();
mXparser::consolePrintln("Res 1: " + e1->getExpressionString() + " = " + v1 );
mXparser::consolePrintln("Res 2: " + e2->getExpressionString() + " = " + v2 + ", bits = " + mXparser::convDecimal2OthBase(v2, 2));

Code result
