Problems Adding two double numbers

Question

I have very stupid issue i am simply taking input of on double and adding it to other double which is already declared and assign a value but sum is not showing floating point

double d = 4.0;
// Getting second double from user
double numDouble = Double.Parse(Console.ReadLine());

//Printing double number :
Console.WriteLine(d + numDouble);

result is always 4.0 + 2.0 = 6 but i want 6.0 any idea

Take a look at MSDN for more information: https://msdn.microsoft.com/en-us/library/kfsatb94(v=vs.110).aspx — Kevin, Mar 29 '16 at 09:23

Math says, that

 6 = 6.0 = 6.00 = 6.000 = ...

so what you want is a representation of double value as a string:

 // F1: - one digit after decimal point
 Console.WriteLine((d + numDouble).ToString("F1"));

Here's another way to format your string for the output.

Console.WriteLine(String.Format("{0:0.0}", (d + numDouble)));
