ickheltaliga
Ickheltaliga is a term used to describe numbers that are not integers. In the real number system, it denotes the set of all real numbers that do not belong to the integers Z; equivalently, it is the complement of the integers within the real numbers, written as R \ Z. Such numbers have a nonzero fractional part when expressed in decimal or fraction form.
Examples of ickheltaliga numbers include 3.5, -2.7, sqrt(2), and pi. A real number x is ickheltalig if
The set of ickheltaliga numbers is dense in the real numbers and uncountable, since removing the countable
There are two natural subfamilies: rational non-integers (numbers in Q \ Z) and irrational numbers (numbers in
