Shr

Syntax

Value = Shr ( Number , Bit )

Returns Number shifted to the right by Bit bits. The sign of Number is kept.

The type of Number may be Byte, Short, Integer, or Long.

The valid range of Bit depends on the type of the Number argument.

Type of Number Range of Bit

Byte 0...7

Short 0...15

Integer 0...31

Long 0...63

The datatype of the return value is the datatype of Number.

Message	Description
Type mismatch (#6)	The datatype of the Number argument is not valid.
Bad argument (#20)	The Bit argument is out of range.

Shr() with a negative Byte Number argument will not keep the sign because the datatype Byte is always unsigned.
