## Purpose

## Return value

## Syntax

`=BITRSHIFT(number,shift_amount)`

*number*- The number to be bit shifted.*shift_amount*- The amount of bits to shift to the right, if negative shifts bits to the left instead.

## How to use

Integer underflow results in loss of the least significant bits. For example, if the number 3 is shifted right by one, then the right-most binary bit is truncated and lost. For any bit shift that results in integer overflow, where the result is larger than 2^48 -1, the function returns the #NUM! error.

### How It Works

The *shift_amount* can either be positive or negative. If a negative number is provided, the bits are shifted to the left instead.
