2018-11-16pack.c: cast from double to float can be undefinedshyouhei
Generally speaking, a value of double is not always representable when demoted to a float. ISO C defines what to do when such conversion loses precision, but leaves it undefined when the value is completely out of range. (cf: ISO/IEC 9899:1990 section 6.2.1.4). Because ruby do not have half-precision floating-point types this is not a frequent headache but for pack / unpack, there are specifiers that has something to do with C float types. We have to explicitly care these situations. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65768 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
