Below is the code for JAVA, the code for C# is almost identical.
Case 1: Using built-in constants
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("pi+e");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: pi+e = 5.859874482048838
Case 2: Estimating Moon gravitational acceleration
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("( [G.] * [Moon-M] / [Moon-R]^2 ) * ( [m] / [s]^2 )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: ( [G.] * [Moon-M] / [Moon-R]^2 ) * ( [m] / [s]^2 ) = 1.6247349715841357
Case 3: Getting list of constants
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression();
mXparser.consolePrintln(e.getHelp("constant"));
