Bug #52457 [Opn]: A natural number is any positive non-zero integer

Edit report at http://bugs.php.net/bug.php?id=52457&edit=1 ID: 52457 Updated by: hm2k@php.net Reported by: hm2k@php.net Summary: A natural number is any positive non-zero integer Status: Open Type: Bug Package: Documentation problem PHP Version: Irrelevant Block user comment: N New Comment: Agreed, there's something not quite right, I just couldn't put my finger on it. Cheers. Previous Comments: ------------------------------------------------------------------------ [2010-08-05 03:05:46] cataphract@php.net "non-zero positive integer" is the part that doesn't make sense. 0 is neither positive nor negative. It should read "a natural number is, for this purpose, any positive integer (0 is therefore not included)". ------------------------------------------------------------------------ [2010-07-27 15:33:12] hm2k@php.net Description: ------------ As a user rightly pointed out a couple of years ago (http://www.php.net/manual/en/function.bcpowmod.php#73406), the statement is incorrectly written: "Note: Because this method uses the modulus operation, non-natural numbers may give unexpected results. A natural number is any positive non-zero integer. " Which is directly from the documentation, meanwhile it is else where defined as: "In mathematics, there are two conventions for the set of natural numbers: it is either the set of positive integers {1, 2, 3, ...} according to the traditional definition; or the set of non-negative integers {0, 1, 2, ...} according to a definition first appearing in the nineteenth century." @see http://en.wikipedia.org/wiki/Natural_number Perhaps it should read: "Note: This method uses the modulus operation, which may produce unexpected results if supplied with anything other than a non-zero positive integer." ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52457&edit=1
