BITAND function

This article describes the formula syntax and usage of the BITAND 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.

Description

Returns a bitwise 'AND' of two numbers.

Syntax

BITAND( number1, number2)

The BITAND function syntax has the following arguments.

  • Number1    Required. Must be in decimal form and greater than or equal to 0.
  • Number2    Required. Must be in decimal form and greater than or equal to 0.

Remarks

  • BITAND returns a decimal number.
  • The result is a bitwise 'AND' of its parameters.
  • The value of each bit position is counted only if both parameter's bits at that position are 1.
  • The values returned from the bit positions progress from right to left as powers of 2. The rightmost bit returns 1 (2^0), the bit to its left returns 2 (2^1), and so on.
  • If either argument is less than 0, BITAND returns the #NUM! error value.
  • If either argument is a non-integer or is greater than (2^48)-1, BITAND returns the #NUM! error value.
  • If either argument is a non-numeric value, BITAND returns the #VALUE! error value.
