There is nothing unclear about what you're saying... it's just a pointless remark. The fact that he suggested binary representation and then went on to show hexadecimal in his example only shows that he doesn't care what form you give him the answer. You're pointing out something completely irrelevant and trying to claim that it would lead people to giving bad information. The fact is that any which way his point might lead someone to answer... the answer is still going to be correct, just in a different form.
It's been completely apparent since your first post that you're just nitpicking. However, instead of actually nitpicking a genuine flaw, you're just nitpicking a choice of words that ultimately have no relevance to the content of the question asked.
I mean after reading two responses that answered his question correctly... do you honestly believe anyone was mislead by the question?
