# How to Use BITOR function in Google Sheets in 2020?

BITOR functionThe BITOR function returns the bitwise Boolean OR of 2 numbers. The BITOR truth table is below:

Parts of a BITOR function

BITOR(value1, value2)

Part
Description
Notes

value1
The first number.

The given value must be a decimal representation of the number.

value2
The second number.

The given value must be a decimal representation of the number.

Sample formulas

BITOR(9, 5)

BITOR(A1, 10)

BITOR(A1, B1)

Notes

It may make sense to use BITOR in conjunction with BIN2DEC as BITOR(BIN2DEC(“1011”), BIN2DEC(“1001”)), which evaluates to “1011” in binary or 11 in decimal.

Examples

In the following example, 9 in binary is “1001” and 5 in binary is 0101. The bitwise OR of 1001 and 0101 is 1101, which is 13 in decimal.
