Is infinity an imaginary number

no... because there is no such ting as infinity being a number ______________________________________________________________ Contributer 2: That's a right answer from contributer 1. But if you are really paranoid and desperately want to find out what infinity is, prepare to have your mind blown. This is not real #'s we are talking about. x/0 would equal infinity and -x/o equals negative infinity. We are assuming 0 is the threshold. This is not incorrect, simply very advanced.
