The numbers to print are:

using System;

class FloatingPointNumbers
    static void Main()
        decimal a = 3.141592653589793238M;
        double b = 1.60217657;
        decimal c = 7.8184261974584555216535342341M;

        Console.WriteLine("{0}\n{1}\n{2}", a, b, c);

Be careful as float (32-bits) - shows 7 numbers;

double (64-bits) shows 15-16 numbers;

the biggest is decimal (128-bit) - 28 to 29 numbers

class FloatOrDouble
    static void Main()
        double a = 34.567839023;
        float b = 12.345f;
        double c = 8923.1234857;
        float d = 3456.091f;

        Console.WriteLine("{0}\n{1}\n{2}\n{3}\n", a, b, c, d);
