When decimal numbers are within the range of 0 to 9, their binary and BCD representations are identical, requiring only four bits (0000 to 1001).

Warnings Excel will only produce binary numbers with up to 10 bits. This means that it can only convert decimal numbers greater than -513 and less than 512.

The purpose of the Bin2Hex engineering function in Excel is to convert a binary or decimal to hexadecimal. Learn how to use it properly.
