Is #5# a rational, irrational, natural, whole, integer or real number?

Answer 1

Eli Assouline

It can be assigned to all above groups except irrational numbers.

The sets mentioned in points 2 and 3 include the ones mentioned above (#NN sub ZZ sub QQ#)

#5# consists of digits only so it is natural, but as mentioned above it is also integer, rational and real.
