The western "natural number" is translated as the so-called "natural number". In mathematics teaching before 1980s and 1990s, natural numbers still did not include 0. But domestic now includes 0.

In Richter's dictionary: integer: any natural number (positive or negative) or zero.

Integer: Any positive or negative natural number or zero.

Webster's Dictionary: {Integer} (Mathematics. ), which is not a fraction or a mixed number; Integer

Integer (mathematics): a number that is not a fraction or a fraction; integer

It can be seen that the western natural number "natural number" is a positive integer, excluding 0.

"Integer" is an integer, including positive integer, negative integer and zero (called positive natural number, negative natural number and zero in the west), rather than the "natural number" in teaching in China at present.

Integer translates into "integer" (mathematics) or "integer" (computer). Mathematically, it means integer, which means the same as integer.

I think I should make it clear.
