Below is the code for JAVA, the code for C# is almost identical.

Case 1: Random integer

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("[Int]");
mXparser.consolePrintln("Res. 1: " + e.getExpressionString() + " = " + (int)e.calculate());
mXparser.consolePrintln("Res. 2: " + e.getExpressionString() + " = " + (int)e.calculate());

[mXparser-v.5.0.0] Res. 1: [Int] = 442074650
[mXparser-v.5.0.0] Res. 2: [Int] = 1214159232

Case 2: Random integer N: -10^k <= N <= 10^k for k = 1, 2, …,9

/* -100 <= N <= 100 */
Expression e2 = new Expression("&#91;Int2&#93;");
mXparser.consolePrintln("Res. 1: " + e2.getExpressionString() + " = " + e2.calculate());
mXparser.consolePrintln("Res. 2: " + e2.getExpressionString() + " = " + e2.calculate());
/* -100000 <= N <= 100000 */
Expression e5 = new Expression("&#91;Int5&#93;");
mXparser.consolePrintln("Res. 3: " + e5.getExpressionString() + " = " + e5.calculate());
mXparser.consolePrintln("Res. 4: " + e5.getExpressionString() + " = " + e5.calculate());
&#91;/java&#93;

[mXparser-v.5.0.0] Res. 3: [Int5] = 98.0
[mXparser-v.5.0.0] Res. 4: [Int5] = -9073.0

Case 3: Random natural number

import org.mariuszgromada.math.mxparser.*;
...
/* Including 0 */
Expression e1 = new Expression("[nat]");
mXparser.consolePrintln("Res. 1: " + e1.getExpressionString() + " = " + (int)e1.calculate());

mXparser.consolePrintln("Res. 4: " + e2.getExpressionString() + " = " + (int)e2.calculate());

[mXparser-v.5.0.0] Res. 1: [nat] = 575008372

[mXparser-v.5.0.0] Res. 3: [Nat] = 1456379413
[mXparser-v.5.0.0] Res. 4: [Nat] = 317300480

Case 4: Random natural number N <= 10^k for k = 1, 2, …,9

import org.mariuszgromada.math.mxparser.*;
...
/* Including 0: 0 <= N < 10 */
Expression e1 = new Expression("[nat1]");
mXparser.consolePrintln("Res. 1: " + e1.getExpressionString() + " = " + (int)e1.calculate());
mXparser.consolePrintln("Res. 2: " + e1.getExpressionString() + " = " + (int)e1.calculate());
/* Excluding 0: 0 < N < 1000 */
Expression e2 = new Expression("[Nat3]");
mXparser.consolePrintln("Res. 3: " + e2.getExpressionString() + " = " + (int)e2.calculate());
mXparser.consolePrintln("Res. 4: " + e2.getExpressionString() + " = " + (int)e2.calculate());

[mXparser-v.5.0.0] Res. 1: [nat1] = 0
[mXparser-v.5.0.0] Res. 2: [nat1] = 7
[mXparser-v.5.0.0] Res. 3: [Nat3] = 726
[mXparser-v.5.0.0] Res. 4: [Nat3] = 265

Case 5: Uniform continuous distribution U(0,1)

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("[Uni]");
mXparser.consolePrintln("Res. 1: " + e.getExpressionString() + " = " + e.calculate());
mXparser.consolePrintln("Res. 2: " + e.getExpressionString() + " = " + e.calculate());

[mXparser-v.5.0.0] Res. 1: [Uni] = 0.2880787240212339
[mXparser-v.5.0.0] Res. 2: [Uni] = 0.13848791690555995

Case 6: Normal distribution N(0,1)

import org.mariuszgromada.math.mxparser.*;
...
Expression e = new Expression("[Nor]");
mXparser.consolePrintln("Res. 1: " + e.getExpressionString() + " = " + e.calculate());
mXparser.consolePrintln("Res. 2: " + e.getExpressionString() + " = " + e.calculate());

[mXparser-v.5.0.0] Res. 1: [Nor] = -2.43166680373401
[mXparser-v.5.0.0] Res. 2: [Nor] = 0.6602054150950812
