Sometimes we need to match the binary number to the decimal number. But for people like me who is not that sensitive to binary, it seems they are all the same… So I need to write a table to match them. It is easy since binary has only 2 digits, 0 or 1. But the calculation could be nasty, and the layout would be annoying when the quantity gets bigger. And when the layout gets annoying, we will make mistakes. And nobody loves mistake.
But there is a simple way we can make this procedure in to a no-brainer. Let’s write down a 4-bits binary and decimal match table. Just check the one below. It is simple, isn’t it? Do you find any pattern?
