BITOR function
This article describes the formula syntax and usage of the BITOR function in Microsoft Excel.
Description Returns a bitwise 'OR' of two numbers.
Syntax BITOR(number1, number2) The BITOR function syntax has the following arguments.
Where A and B are inputs and X is the result. The result for each bit combination is as per the table below:
Example Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
How is it Calculated?
21 in Binary : 10101
10 in Binary : 01010
10101 OR
01010
=11111
Decimal of 11111 : 31
This article describes the formula syntax and usage of the BITOR function in Microsoft Excel.
Description Returns a bitwise 'OR' of two numbers.
Syntax BITOR(number1, number2) The BITOR 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.
- The result is a bitwise 'OR' of its parameters.
- In the result, each bit position is 1 if any of the 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 the left returns 2 (2^1), and so on.
- If either argument is outside their constraints, BITOR returns the #NUM! error value.
- If either argument is greater than (2^48)-1, BITOR returns the #NUM! error value.
- If either argument is a non-numeric value, BITOR returns the #VALUE! error value.
Where A and B are inputs and X is the result. The result for each bit combination is as per the table below:
| A | B | X |
| 0 | 0 | 0 |
| 0 | 1 | 1 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
Example Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
| Formula | Description | Result |
| =BITOR(21,10) | Returns the total of the bitwise "Or" operation at each bit position. | 31 |
| =BITOR(21,15) | Returns the total of the bitwise "Or" operation at each bit position. | 31 |
| =BITOR(11,8) | Returns the total of the bitwise "Or" operation at each bit position. | 11 |
