Re: [RFC] Config setting to force all math operations to pass through BCMath library.

Michael, I'm with Anthony, in that you shouldn't change behaviour of this nature with an ini setting. I would bring more pain than what it takes away. This is one of those gotchas that everyone comes across, like you noted. The main issue is that floating point arithmetic != real number arithmetic; and bc functions do solve the issue, but make for some ugly code in complex operations... Since Anthony mentioned Python, maybe the discussion should be if PHP should/could support decimal like Python does http://docs.python.org/library/decimal Now that would be something interesting to see discussed!!
