In Swift, is Bool considered to be a numerical type?

I just did a quiz in Swift basics where the question was "Which of the following is not a numerical type?" A. Int B. Float C. Double D. Bool E. None of These

The correct answer was E. None of These, but Initially I chose D. Bool, which was incorrect. I understood Bool to represent true or false, not a numerical type. I'm confused as to why Bool was not the correct answer?

Hi Christian,

the boolean type stems from the binary numbering system and can be translated into true == 1 false == 0 which is why it is defined as a numerical type.

Thank you so much for this answer! I was really confused so I honestly didn't get it.
