BTW, strictly speaking, shouldn't I be adding something to the floating

I potentially classify a composite as a prime?
You could avoid sqrt using divmod (which gets the % result too); stop
when quotient<=divisor.
But this approach creates a tuple and then unpacks it, so you should
time it to see if there is an actual speed improvement.
