Argument Explanation

Number – Give the binary number that you want to convert to a decimal number. But it should contain only ten characters. You can use positive or negative integers. We can represent negative numbers in 2’s complement notation.

Note:
1) If the input number contains more than ten digits, it will display the #NUM! Error.
2) If the input value is an invalid binary number (other than zeros and ones), it may show the #NUM! Error.

## Examples

Let’s see some examples to know how to use the BIN2DEC function in Microsoft Excel.

• Initially, you have to open your Excel workbook on your PC and launch a worksheet that has data.
• The first bit of the binary number shows whether it is a positive number or a negative number.
• If the binary value starts at 0, it is a positive number. In the following image, we have shown you some positive decimal numbers for your reference in a range.
• Now, we need to enter the above-mentioned formula to get the result.
• After entering the formula, you need to click the button to get the output, as shown below. To fill the remaining cells, you just need to drag down the first cell.
