In this article, we will learn about how to use the BITLSHIFT function in Excel.
BITLSHIFT function in excel perform the Bitwise Left Shift operation on a decimal number and returns the decimal number after the operation performed.
Bitwise left shift operation is performed on a binary number. Let’s consider a decimal number 4 and bit left shift to be 2. As we know 4 is represented as 100 in binary. So 2 zeros will be added to the right of the binary number by shifting left.
|Number||Binary number||shift_amount||Binary number after shift||Number after shift|
The BITLSHIFT function returns a Bitwise Left Shift of a decimal number upto shift_amount.
number1 : a positive integer number of base 10 (decimal number) to be shifted
shift_amount : an integer representing the amount of shift to occur on the number. This argument can be positive , zero or negative.
Here is the excel representation of the function
As you can the function returns 16 after the bitwise left shift of 2 on 4.
You can use the DEC2BIN & BIN2DEC function in excel to understand the conversion operation.
Now let’s get more understanding of the function via using them in some examples.
Here we have some values as number & shift_amount in Columns. We need to get the bitwise left shift operation on the given numbers using the BITLSHIFT function in excel
Use the formula :
A2 : number provided to the function as cell reference
B2 : number provided to the function as cell reference
The bitwise left shift operation on 1 ( 01 ) by adding one zero to the right of the number will be 2 ( 010 ).
Now copy the formula to other cells using the Ctrl + D shortcut key.
As you can see here the BITLSHIFT function returns the result of the input values.
