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: Random integer

Case 2: Random integer N: -10^k <= N <= 10^k for k = 1, 2, …,9
/* -100 <= N <= 100 */ Expression e2 = new Expression("[Int2]"); mXparser.consolePrintln("Res. 1: " + e2.getExpressionString() + " = " + e2.calculate()); mXparser.consolePrintln("Res. 2: " + e2.getExpressionString() + " = " + e2.calculate()); /* -100000 <= N <= 100000 */ Expression e5 = new Expression("[Int5]"); mXparser.consolePrintln("Res. 3: " + e5.getExpressionString() + " = " + e5.calculate()); mXparser.consolePrintln("Res. 4: " + e5.getExpressionString() + " = " + e5.calculate()); [/java] <!-- /wp:shortcode --> <!-- wp:shortcode --> [mXparser-v.5.0.0] Res. 1: [Int2] = -48.0 [mXparser-v.5.0.0] Res. 2: [Int2] = -3.0 [mXparser-v.5.0.0] Res. 3: [Int5] = 98.0 [mXparser-v.5.0.0] Res. 4: [Int5] = -9073.0

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