BIT_SHIFT_RIGHT

Shifts the bits in the first argument to the right by n bits, where n is the second argument. Shifting right by n positions is equivalent to dividing the number by 2^n.

Syntax

BIT_SHIFT_RIGHT(<value>, <bits>)

Parameters

Parameter	Description	Supported input types
<value>	Specifies the value to shift.	INT, BIGINT
<bits>	The number of bits to shift.	INT

Return Types

The BIT_SHIFT_RIGHT function returns a result of either type INT or BIGINT, depending on the type of the input <expression>.

Examples

Example

The following code example shifts 0001, the binary representation of 1, to the right by two bits, which yields 0000, the binary representation for 0:

SELECT bit_shift_right(1, 2) AS res;

Returns

res (INTEGER)
0

Example

The following code example shifts 00101, the binary representation of 5, to the right by two bits, which yields 00001, the binary representation for 1:

SELECT bit_shift_right(5, 2) AS res;

Returns

res (INTEGER)
1

Example

The following code example shifts the binary representation of -3, which is 1111111111111101 in signed two’s complement, one bit to the right, resulting in 1111111111111110, the signed two’s complement of -2:

SELECT bit_shift_right(-3, 1) AS res;

Returns

res (INTEGER)
-2
