Calculation Steps Register

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! 🙂

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.

Calculation is a multi-step process and the CalculationStepsRegister class provides a register to store all the steps as a collection of CalculationStepRecord, also done in a recursive way.

Case 1: Simple Expression

Java/C# code

// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("2*(3+4)+5");
CalcStepsRegister calcStepsRegister = new CalcStepsRegister();

mXparser.consolePrintln(e.getExpressionString() + " = " + e.calculate(calcStepsRegister));
mXparser.consolePrintln("----");

/* Printing content of all the calculation steps */
for (CalcStepRecord step : calcStepsRegister.calcStepRecords)
	mXparser.consolePrintln(step.content);

C++ code

#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("2*(3+4)+5");
CalcStepsRegisterPtr calcStepsRegister = new_CalcStepsRegister();

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

/* Printing content of all the calculation steps */
for (const CalcStepRecordPtr &step : *calcStepsRegister->calcStepRecords)
    mXparser::consolePrintln(step->content);

Code result

[mXparser-v.5.2.1] 2*(3+4)+5 = 19.0
[mXparser-v.5.2.1] ----
[mXparser-v.5.2.1] 2*(3+4)+5

Case 2: Dependent User Argument

Java/C# code

mXparser.consolePrintln("----");

for (CalcStepRecord step : calcStepsRegister.calcStepRecords)
	mXparser.consolePrintln(step.numberGroupWithin + ". " + step.content);

C++ code

mXparser::consolePrintln("----");

for (const CalcStepRecordPtr &step : *calcStepsRegister->calcStepRecords)
    mXparser_consolePrintln(step->numberGroupWithin + ". " + step->content);
