Conversion of binary to decimal numbers is often needed in firmware. And it’s done easily enough if multiplication and division by ten are acceptable.

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.

Why? Because it is simpler for computers to convert from binary and hexadecimal and vice versa, and it is significantly harder to do this with the commonly-used decimal number system.
