# >> Operator (C# Reference)

**Visual Studio 2005**

The right-shift operator (**>>**) shifts its first operand right by the number of bits specified by its second operand.

If the first operand is an int or uint (32-bit quantity), the shift count is given by the low-order five bits of the second operand (second operand & 0x1f).

If the first operand is a long or ulong (64-bit quantity), the shift count is given by the low-order six bits of the second operand (second operand & 0x3f).

If the first operand is an int or long, the right-shift is an arithmetic shift (high-order empty bits are set to the sign bit). If the first operand is of type uint or ulong, the right-shift is a logical shift (high-order bits are zero-filled).

User-defined types can overload the **>>** operator; the type of the first operand must be the user-defined type, and the type of the second operand must be int. For more information, see operator. When a binary operator is overloaded, the corresponding assignment operator, if any, is also implicitly overloaded.
