Bug->Doc #61643 [Opn->Ana]: gmp_nextprime and gmp_dcdext behavior differences

Edit report at https://bugs.php.net/bug.php?id=61643&edit=1 ID: 61643 Updated by: ab@php.net Reported by: mattficken@php.net Summary: gmp_nextprime and gmp_dcdext behavior differences -Status: Open +Status: Analyzed -Type: Bug +Type: Documentation Problem Package: GNU MP related PHP Version: 5.4.1RC1 Block user comment: N Private report: N New Comment: I'm using this snippet to test on both Windows and Linux #include <gmp.h> int main (void) { mpz_t p; mpz_init_set_str(p, "-1000", 10); mpz_nextprime(p, p); gmp_printf("mpz_nextprime : %Zd\n", p); return 0; } It looks like the correct answer is 2, on both windows mpir 2.5.1 and 2.6.0 and linux with gmp. The tests are also pass now, the doc is wrong. Previous Comments: ------------------------------------------------------------------------ [2012-04-05 21:21:07] mattficken@php.net Description: ------------ 022.phpt which tests gmp_gcdext() and gmp_nextprime.phpt which tests gmp_nextprime() fail on Windows but pass on Linux. The returned value of both of those functions in some cases doesn’t match the expected value(in some cases it does). In example #1 in the documentation for gmp_nextprime() (http://us3.php.net/gmp_nextprime), gmp_nextprime(-1000) returns -997 however on Linux it returns 2, which is what the test expects so the test passes. Not only is this a behavior difference between Windows and Linux but is not what the documentation states ( gmp_nextprime(-1000) => -997 not 2). ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=61643&edit=1
