But in case 100, I wrote below.\[code\]http://github.com/sanemat/kata-fibonacci-phpunit/commit/b6b2945d2eff1b95e7e25b8be8c7bff11098d44d\[/code\]I expect this return TRUE.It failed.\[code\]http://www.php.net/manual/en/language.types.float.php\[/code\]I understood 'never compare for equality.' and so how to aseert it?At the end, I compare with to_string each other.How to compare large number in PHP ?\[code\]http://github.com/sanemat/kata-fibonacci-phpunit/commit/70a0e47bc0737be47da8fe8726634edd851d940d\[/code\]I feel it as bad smell.
