Does anyone know how to use the _rotl function or if there
an equivalent in C# ?

Anything wrong with using the left shift operator?

int x = y << z;

 

[Guest]

The shift operation replaces the shifted bits by 0
What I would like is that the shifted bit goes to the right of the byte

Any idea

Thank

The shift operation replaces the shifted bits by 0.

What I would like is that the shifted bit goes to the right of the byte.

(x << z) | (x >> (32 -z))

Ah, I see. Sorry! Well, you could do:

public static uint RotateLeft (uint original, int bits)
{
return (original << bits) | (original >> (32-bits));
}

Does that help?

nice one... only I was 28 seconds faster... )
