BITAND function

BITAND function



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