You agree that the numbers are real? But you do not agree that these

And you have already forgotten that finite integers are real numbers?

Read § 4, first sentence:
Die erweiterte ganze Zahlenreihe kann, wenn es die Zwecke fordern,
ohne weiteres zu einer kontinuierlichen Zahlenmenge vervollständigt
werden, indem man zu jeder ganzen Zahl alle alle reellen Zahlen x, die
größer als Null und kleiner als Eins sind, hinzufügt.
Obviously these extended numbers are not ordinals or cardinals -
unless sets can have fractions of elements.
