Re: Terminology of integers

Thanks to Lee Rudolph. He is right about van der Waerden's usage. And ``quantity'' is a better translation than ``magnitude.''
It seems that in current German algebra the word ``ganz/integer'' is only an adjective. Writers say ``integer number'' or ``integer element'' or ``integer quantity'' in a number field or a function field. In English, in number fields, people say ``integer'' but in function fields they prefer ``integral function'' and the like. For a translation I expect to use "integer" as a noun for Noether's ``ganz Grosse'' in number fields, and since she uses the phrase just once of function fields I'll translate it the same way.
best, Colin
