BITLSHIFT function: Description, Usage, Syntax, Examples and Explanation
What is BITLSHIFT function in Excel?
BITLSHIFT function is one of Engineering functions in Microsoft Excel that returns a number shifted left by the specified number of bits.
Syntax of BITLSHIFT function
The BITLSHIFT function syntax has the following arguments.
- Number Required. Number must be an integer greater than or equal to 0.
- Shift_amount Required. Shift_amount must be an integer.
BITLSHIFT formula explanation
- 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.
Example of BITLSHIFT function
Steps to follow:
1. Open a new Excel worksheet.
2. Copy data in the following table below and paste it in cell A1
Note: For formulas to show results, select them, press F2 key on your keyboard and then press Enter.
You can adjust the column widths to see all the data, if need be.
|Formula||Description||Result||How it works|
|=BITLSHIFT(4,2)||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.||16||4 is represented as 100 in binary. Adding two 0 digits to the right results in 10000, which is 16 in decimal.|
