As I said, you passed over the problem at issue in silence.

A bad translation; it's not the domain that is real, but the numbers:
better is "a definite extension of the region of real numbers into the
And what does this give? an ordered set; but no multiplication
defined here, of course!
Indeed, when (ordinal) multiplication is introduced (section 3), it is
in the context of Cantor's number classes:
"The first number-class (I) is the set of finite integers
1,2,3, ...,nu,..., which is followed by a second number-class
consisting of certain infinite integers following each other
in a determined succession; after defining the second number-class,
the third is reached, then the fourth etc."
(translation George Bingley)
3.14159... does not make an appearance anywhere in these number classes.
