To me that is not clear. >=20 > That's why I pointed out that _zero is a number_. Those are big words :-) Minus one is also a number, but we'd be hard pressed to come up with a function taking minus one arguments. Three-quarters, the square root of two and pi are numbers. Arguably, "the" Chaitin constant [1] (actually there are many of them)is also a number. I think the manual wants to say "natural number" and just says "number", but that's OK, because it is directed at humans, and we humans are usually better at disambiguating given a context than at staying awake in front of long and boring texts. Arguably, "zero or more" might be clearer here, but I don't know (after all, the square root of two is bigger than zero, too). Now mathematicians don't agree on whether zero is a natural number. The faculty I studied in started counting from zero, but I've seen faculties which count from one. I once asked a friend of mine teaching at one uni, and he told me faculties having a strong mathematical logic department tended to start with zero. So zero may be a number or not, at least if you read "number" as "natural number", and you ask a mathematician :) Cheers [1] There are uncountably many horrible monsters in the real numbers: https://en.wikipedia.org/wiki/Chaitin%27s_constant --=20 t --M7nqx84mqUD7Sv+3 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABECAB0WIQRp53liolZD6iXhAoIFyCz1etHaRgUCY8YyFAAKCRAFyCz1etHa RmzOAJ9gEMgG8XLbFsfXfo5ixaJxAqyBsgCggf+9jheNIS8Ip3ssb4bg6oWoKTs= =f1MM -----END PGP SIGNATURE----- --M7nqx84mqUD7Sv+3--
