shrshift right operator

Syntax   A shr B

Description   The shr (shift right) operator produces the value of A shifted B bits to the right. Both A and B must be non-negative integers (natural numbers).

Example   Assign the base 2 value 1101 to i and then shift it right by 2 places and assign the resulting base 2 value 11 to j.

        var i, j : int
        i := 2 # 1101   % 2#1101 = 13 (base 10)
        j := i shr 2        % j becomes 2#11 = 3 (base 10)

Details   The shr operator is defined mathematically (in a machine- independent way) as follows: A shr B = A div 2**B.

Value A can be of any integer type (as long as it is non-negative) or any natural number type.

The shr operator has the same precedence as the * operator.

See also   shl (shift left), or, and and xor, which also are bit manipulation operators that act on non-negative values. See also explicitIntegerConstant which describes values such as 2#1101.
