Below is the code for JAVA, the code for C# is almost identical.
Case 1: The square root √
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("√2");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: √2 = 1.4142135623730951
Case 2: The square root of the square root √√
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("√√16");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: √√16 = 2.0
Case 3: The square root and parenthesis √()
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("√√(8+8)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: √√(8+8) = 2.0
Case 4: The roots of various orders ∜ ∛ √
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("∜16 + ∛27 + √16");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: ∜16 + ∛27 + √16 = 9.0
Case 5: SIGMA summation operator ∑
import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("∑(i, 1, 5, i^2)");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: ∑(i, 1, 5, i^2) = 55.0
Case 6: Unicode name of a user defined argument
import org.mariuszgromada.math.mxparser.*;
...
Argument a = new Argument("α = 2π");
Argument b = new Argument("β = π/2");
Expression e = new Expression("sin(α) + cos(β)", a, b);
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.5.0.0] Res: sin(α) + cos(β) = 0.0
Case 7: Show all Unicode built-in keywords
import org.mariuszgromada.math.mxparser.*;
...
mXparser.consolePrintHelp("unicode");
