◧ Arguments
| Argument | Type | Required | Description |
|---|---|---|---|
number |
Number | Required | Number must be an integer greater than or equal to 0. |
shift_amount |
Number | Required | Shift_amount must be an integer. |
▣ Examples
Shifts bits left for the number by adding zeros (0) to the right of the number represented in binary. The number returned is represented in decimal.
=BITLSHIFT(4,2)
Result:
16
§ Remarks
- Shifting a number left is equivalent to adding zeros (0) to the right of the binary representation of the number. For example, a 2-bit shift to the left on the decimal value 4 converts its binary value (100) to 10000, or 16 in decimal.
- If either argument is outside their constraints, BITLSHIFT returns the #NUM! error value.
- If Number is greater than (2^48)-1, BITLSHIFT returns the #NUM! error value.
- If the absolute value of Shift_amount is greater than 53, BITLSHIFT returns the #NUM! error value.
- If either argument is a non-numeric value, BITLSHIFT returns the #VALUE! error value.
- A negative number used as the Shift_amount argument shifts the number of bits to the right.
- A negative number used as the Shift_amount argument returns the same result as a positive shift_amount argument for the BITRSHIFT function.

⚠ Common Errors
#NUM!
If either argument is outside their constraints, BITLSHIFT returns the #NUM! error value. If Number is greater than (2^48)-1, BITLSHIFT returns the #NUM! error value. If the absolute value of Shift_amount is greater than 53, BITLSHIFT returns the #NUM! error value.
Fix: Enter a non-negative value
#VALUE!
If either argument is a non-numeric value, BITLSHIFT returns the #VALUE! error value.
