------- Comment #20 from rob1weld at aol dot com 2007-06-15 21:23 ------- Created an attachment (id=13709) --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=13709&action=view) Specific example where libm, libcrlibm, and mpfr differ
Here is a specific example of three different math libraries providing three different answers to the same question. The number does not use very many decimal places and thus __could__ come up in common use. It is not really how likely the number would be used that is important but what the result of using the answer would be. If your life is important don't be it on this number. This is just one number. How many more could there be, how will you prove you are correct and deduce the actual correct answer in those instances. This is what you must answer. This is why we need a fast, simple, library that is accurate and comes with "proof". -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32180
