How to generate random floating point numbers in C#

Answer 1

using System;
using System.Collections.Generic;

class Program
{
    // Function to generate N random numbers in the range [lower, upper]
    static List<double> GenerateRandomNumbers(int count, double lower, double upper) {
        var rand = new Random();
        var numbers = new List<double>();

        for (int i = 0; i < count; i++) {
            double num = lower + (upper - lower) * rand.NextDouble();
            numbers.Add(num);
        }

        return numbers;
    }

    static void Main()
    {
        int count = 10;
        double lower = 0.0, upper = 3.0;

        List<double> randomNumbers = GenerateRandomNumbers(count, lower, upper);

        foreach (double num in randomNumbers) {
            Console.Write($"{num:F6} ");
        }

        Console.WriteLine();
    }
}
