While some may see it as a minor point, decimal numbers, if I'm not mistaken, are simply numbers written in base ten. They are not necessarily numbers that are between whole numbers.
For convenience, we tend to refer to .7, .83333..., etc. as decimals, while 7, 8, etc. are whole numbers. But 7, 8, etc. are also decimals.
