BITRSHIFT

Mathematical

## Summary:

Shifts a number right by the specified number of bits. Note: This functions is available since LibreOfficeDev 3.5.

## Syntax:

BITRSHIFT(Number; Shift)

## Returns:

Returns a number shifted right by the specified number of bits.

## Arguments:

Number is a positive integer less than 2 ^ 48 (281,474,976,710,656).

Shift is the number of positions the bits will be moved to the right. If shift is negative, it is synonymous with BITLSHIFT (Number; -Shift).

• If either argument is a decimal number then its floor value is considered.
• If Number is negative, the function returns an error value.

• Shifting a number right is equivalent to adding zeros (0) to the left of the binary representation of the number. For example, a 1-bit shift to the right on the decimal value 6 converts its binary value (0110) to 0011, or 3 in decimal.
• Using a negative number as the Shift argument shifts the number of bits to the left. Hence it will return the same result as a positive Shift argument for the BITLSHIFT function.

## Examples:

Formula Description Returns
=BITRSHIFT(15;3) 15 in binary is 1111 which when applied with right shift by 3-bit gives 0001 or (1111 >> 3 = 0001) 1 (0001)
=BITRSHIFT(6;-1) 6 in binary is 0110 which when applied with right shift by -1-bit gives 1100 which is equivalent to left shift by 1-bit or (0110 >> -1 = 1100) 12 (1100)
=BITRSHIFT(15.123;3) floor of 15.123 is taken so 15 in binary is 1111 which when applied with right shift by 3-bit gives 0001 or (1111 >> 3 = 0001) 1 (0001)
=BITRSHIFT(15;3.7) 15 in binary is 1111 which when applied with right shift by 3-bit(floor of 3.7 is considered) gives 0001 or (1111 >> 3 = 0001) 1 (0001)
=BITRSHIFT(-15;3) Number is negative so function returns error value Err:502
