BITRSHIFT function

This article describes the formula syntax and usage of the BITRSHIFT function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.


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


BITRSHIFT(number, shift_amount)

The BITRSHIFT function syntax has the following arguments.

  • Number    Required. Must be an integer greater than or equal to 0.
  • Shift_amount    Required. Must be an integer.


  • Shifting a number right is equivalent to removing digits from the rightmost side of the binary representation of the number. For example, a 2-bit shift to the right on the decimal value 13 converts its binary value (1101) to 11, or 3 in decimal.
  • If either argument is outside its constraints, BITRSHIFT returns the #NUM! error value.
  • If Number is greater than (2^48)-1, BITRSHIFT returns the #NUM! error value.
  • If the absolute value of Shift_amount is greater than 53, BITRSHIFT returns the #NUM! error value.
  • If either argument is a non-numeric value, BITRSHIFT returns the #VALUE! error value.
  • A negative number used as the Shift_amount argument shifts the number of bits to the left.
  • A negative number used as the Shift_amount argument returns the same result as a positive Shift_amount argument for the BITLSHIFT function.
