IN this article, we will understand How to use the BITLSHIFT Function in Excel
This function was introduced in Excel 2013 and it returns a number shifted left by bits specified as numbers. For example, binary representation of 8 is 1000 and adding two 0 digits on the right of it will make it as 100000, which is number 32 in decimal.
The BITLSHIFT function in excel performs the Bitwise Left Shift operation on a decimal number and returns the decimal number after the operation is performed. Bitwise left shift operation is performed on a binary number. Let’s consider a decimal number 4 and a 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.
|=BITLSHIFT ( number, 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 :
|=BITLSHIFT (A2, B2)|
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.
