I'm going to lay out what numbers are what. For programming purposes these
definitions vary.
All Numbers
Imaginary: Numbers that do not exist for practical purposes. They have real
value in some engineering fields, and in mathematics. What number, when
multiplied with itself gives you a negative result. That would be an
imaginary number.
Real: All numbers that are either negative or positive. No imaginary
numbers are real numbers.
Rational: All numbers that can be put in fraction form.
Irrational All numbers that cannot be put in fraction form.
Integers: All numbers that do not contain a decimal point
Whole: All numbers that are integers and are not negative
Natural: All numbers that are integers and are not negative and are not
zero.
