Summary

Performs an arithmetic right shift.

Pascal

 function Sar(const Value: Shortint; const Count: TBitRange): Shortint; overload;
function Sar(const Value: Smallint; const Count: TBitRange): Smallint; overload;
function Sar(const Value: Integer; const Count: TBitRange): Integer; overload;

Parameters

Parameters	Description
const Value: Shortint	The Value whose bits to arithmetically shift.
const Count: TBitRange	Number of positions to right shift.

Return Value

A copy of value after the arithmetic right shift operation.

Description

Sar performs an arithmetic right shift on the operand. An arithmetic right shift is similar to a logical right shift (shr) except that shr operates on unsigned values while Sar operates on signed values (and as such preserves the sign).
