[RESOLVED] Shift Operators (>> and <<)

[sevenhalo]

I've been dabbling in C# a bit and this has me really stuck against a wall.

class Test 
{
   public static void Main() 
   {
      int i = -1000;
      Console.WriteLine(i >> 3);
   }
}

According to MSDN, this shows -125

Could someone please explain to me how this works?

Thanks in advance

-1000 in Signed int32:
10000000 00000000 00000011 11101000

Shift Right 3 (Inv+Lsh on calc)
10000000 00000000 00000000 01111101

Which is -125

Got it, thanks!

Be careful with that.. You might want to look, but I recall reading there is still a bug in the RTM versions of C# when using the shift operator inside of parentheses like that.. I'll see if I can remember where I found it.

I'm only trying to translate some C# to VB. I'm not actually going to be using the operators, just mimicing the functionality in my own class.

Thanks for the heads up though

this is what I was thinking of. So, atleast it doesn't produce bad code.(and it was in VB at that)
