Question

why can’t I assign 1.2 value to float variable in C#? I did the same in C and C++, and it worked.

class Program
{
    private readonly int a = 20;
    private readonly float b;      

    public Program(float tmp)
    {
        b = tmp;
    }
    static void Main(string[] args)
    {
        Program obj1 = new Program(1.2);
        Console.Read();
    }
}

It gives error can not convet double to float.
Why is so isn’t 1.2 float value?

Answer 1

1.2 is a double (8 bytes).
1.2f is a float (4 bytes).
