Re: GMP and empty()

Hi all, I thought GMP object does not work with math functions, but some of them work. Apparently, I was only testing with function that does not work with GMP. Some math function works. e.g. pow() with small value. min()/max() seems ok. Not only empty(), but there are number of wired behavior with GMP and functions. I haven't tried them all, but we need to work more for these. It seems time to write more tests and fix issues. === pow() === [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("2"); var_dump(pow($v, 10));' int(1024) This works fine. [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("223423"); var_dump(pow($v, 234242));' float(INF) This returns float(INF). It may be acceptable. Returning GMP object with correct value is better. [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("223423423423423423423422342342342342.234234234"); var_dump(pow($v, 234242));' int(0) but this returns int(0). === round()/floor()/ceil()=== [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("25.234242342"); var_dump(round($v));' float(0) It should be 25. floor()/ceil() is the same. ===abs()=== [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("25.234242342"); var_dump(abs($v));' int(0) It returns int(0). ===acos()=== [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("25.234242342"); var_dump(acos($v), acos(25.234242342));' float(1.5707963267949) float(NAN) Something wrong. ===cos()=== [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("25.234242342"); var_dump(cos($v), cos(25.234242342));' float(1) float(0.99485318302495) Almost correct, but it's not. If GMP integer is passed, it raises E_WARNING. [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("2"); var_dump(cos($v), cos(2));' Warning: cos() expects parameter 1 to be double, object given in Command line code on line 1 NULL float(-0.41614683654714) ===log=== [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("2"); var_dump(log($v), log(2));' Warning: log() expects parameter 1 to be double, object given in Command line code on line 1 NULL float(0.69314718055995) [yohgaki@dev php-src]$ ./php-bin -d error_reporting=-1 -r '$v = gmp_init("2.2"); var_dump(log($v), log(2.2));' float(-INF) float(0.78845736036427) Something wrong. ​
