THANK YOU!
The tutorial consists of more than 200 live examples from 50 sections. 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, the code for C# is almost identical.
Case 1: Simple calculation
$$2+1$$
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2+1");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: 2+1 = 3.0
Case 2: Changing expression string
$$2-1$$
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2+1");
e.setExpressionString("2-1");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: 2-1 = 1.0
Case 3: Using operators
$$2-\frac{32-4}{23+\frac{4}{5}}-(2-4)(4+6-98.2)+4$$
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2-(32-4)/(23+4/5)-(2-4)*(4+6-98.2)+4");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: 2-(32-4)/(23+4/5)-(2-4)*(4+6-98.2)+4 = -171.57647058823528
Case 4: Power function
$$2^3+2^{3}+2^{3^{-4}}$$
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("2^3+2^(-3)+2^3^(-4)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: 2^3+2^(-3)+2^3^(-4) = 9.133594091576999
Case 5: Using numbers in scientific notation
import org.mariuszgromada.math.mxparser.*;
...
Expression e1 = new Expression("1.2e2 + 1.2e+2 + 1.2e-2");
mXparser.consolePrintln("Res 1: " + e1.getExpressionString() + " = " + e1.calculate() );
Expression e2 = new Expression("1.2E2 + 1.2E+2 + 1.2E-2");
mXparser.consolePrintln("Res 2: " + e2.getExpressionString() + " = " + e2.calculate() );
[mXparser-v.5.0.0] Res 1: 1.2e2 + 1.2e+2 + 1.2e-2 = 240.012
[mXparser-v.5.0.0] Res 2: 1.2E2 + 1.2E+2 + 1.2E-2 = 240.012
Case 6: Percent sign support
import org.mariuszgromada.math.mxparser.*;
...
Expression e1 = new Expression("2%");
Expression e2 = new Expression("2% * 100");
Expression e3 = new Expression("pi% * 100");
mXparser.consolePrintln("Res 1: " + e1.getExpressionString() + " = " + e1.calculate());
mXparser.consolePrintln("Res 2: " + e2.getExpressionString() + " = " + e2.calculate());
mXparser.consolePrintln("Res 3: " + e3.getExpressionString() + " = " + e3.calculate());
[mXparser-v.5.0.0] Res 1: 2% = 0.02
[mXparser-v.5.0.0] Res 2: 2% * 100 = 2.0
[mXparser-v.5.0.0] Res 3: pi% * 100 = 3.1415926535897936
Case 7: Leading zeros support
import org.mariuszgromada.math.mxparser.*;
...
Expression e1 = new Expression("00123");
Expression e2 = new Expression("-00123");
Expression e3 = new Expression("-00000123.123e-10");
mXparser.consolePrintln("Res 1: " + e1.getExpressionString() + " = " + e1.calculate());
mXparser.consolePrintln("Res 2: " + e2.getExpressionString() + " = " + e2.calculate());
mXparser.consolePrintln("Res 3: " + e3.getExpressionString() + " = " + e3.calculate());
[mXparser-v.5.0.0] Res 1: 00123 = 123.0
[mXparser-v.5.0.0] Res 2: -00123 = -123.0
[mXparser-v.5.0.0] Res 3: -00000123.123e-10 = -1.23123E-8
Case 8: Fractions support
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("1_2 + 2_1_2");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.1.0] Res: 1_2 + 2_1_2 = 3.0
