The server really doesn't care - those examples are equivalent. It really comes down to what makes the most sense to the humans involved.

For something that's "just a number" then the decimal version makes sense. If it's something more readable in hex then use one of the hex formats.

You could also use a string. E.g. "AA" is (if I remember my codes after a long day) the same as 0x4141, or 41:41, or 16705.
