forgive my ignorance, but how come 21.9999999999999 is equal to 22.0? --And. >>> cowan@hidden.email 10/30/02 03:00pm >>> pycyn@hidden.email scripsit: > Well, no.

In some contexts, integer 22 can do business for real 22.0r > but they are different critters (natural 22 is something else again still). I don't agree. Every natural number is an integer; every integer is a real number. 22, 22.0, 22.00000... and 21.99999... are mere notational differences. In short, there is no identity predicate on numbers that is finer than numeric equality. -- "No, John.
