Perhaps I don't speak everyday English.

Most people probably rarely use the word "integer".  When they do,
if they use it correctly, they use it to refer to the set of numbers
with no fractional part, which can be positive, zero, or negative.
I've never heard the word "integer" used in a way that excludes
negative numbers.

The way I was taught in elementary school:

The integers are ..., -2, -1, 0, 1, 2 ...
The natural numbers are 1, 2, ...
The whole numbers are 0, 1, 2, ...

There isn't universal agreement on whether the natural and/or whole
numbers include 0.  Ada, for example, has a subtype Natural whose lower
bound is 0 (Positive starts at 1), which was very slightly jarring when
I first encountered it.
