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.

Fix unpacking with 'b', 'B', 'h' and 'H' format. Do not return an
uninitialized String to Ruby before filling the content bytes.
Fixes r11175 ("pack.c (pack_unpack): execute block if given with
unpacked value instead of creating an array", 2006-10-15).
