Are decimals considered integers whole numbers or natural numbers?

Answer 1

Unless the decimal contains all zeroes to the right of the decimal point (for example, 2.00), it is not an integer, a whole number, or a natural number. The integers are: (...-3, -2, -1, 0, 1, 2, 3, ...); whole numbers are: (0, 1, 2, 3, ...); and natural numbers are: (1, 2, 3, ...). If the decimal is a terminating decimal (e.g., 3.25) or a repeating decimal (e.g., 3.252525252525...), the number is a rational number. If it is a decimal that does not repeat after some number of digits (e.g., pi or sqrt(2)), the number is irrational.
