Why doesn't this work?

Question

double idk;
idk = 3/2;
Console.WriteLine(idk);
Console.ReadLine();

The output is 1 ,

Answer 1

Don't know much C#, but it seems since the two literals are integers (as none of them were written with decimal points) I guess the result of integer division is then assigned to <idk>.

You might want to try divide with floating point literals (3.0/2) or use type indicator (3f/2)

idk = 3.0/2;
idk = 3f/2;

(Edit)
You can also have a double variable to be the left operand here;

double a = 3;
double b = a / 2;
Console.WriteLine(b);

Answer 2

What Ipang says it true.

quotte from the link:
When you divide two integers, the result is always an integer.
