+ <p>compact IEEE 754 double encoding in external binary
+ format for ei</p> <list><item><p>Implement the compact
+ IEEE 754 double encoding in external binary format for
+ ei. Encoding for ei now always produces the NEW_FLOAT_EXT
+ format. Decoding and term printing handle both the old
+ ERL_FLOAT_EXT encoding and the new NEW_FLOAT_EXT
+ encoding. </p></item> <item><p>Legacy erl_interface code
+ also handles the new encoding, but still produces the
+ ERL_FLOAT_EXT encoding by default.</p></item>
+ <item><p>Also enable the DFLAG_NEW_FLOATS distribution
+ flag.</p></item> <item><p>ei_get_type() will return
+ ERL_FLOAT_EXT regardless if the external format is
+ encoded with ERL_FLOAT_EXT or NEW_FLOAT_EXT for
+ doubles.</p></item> <item><p>Reduce the number of copies
+ of the code for encoding and decoding doubles throughout
+ ei and erl_interface by instead calling the ei encoding
+ and decoding functions wherever possible.</p></item>
+ <item><p>Restore commented-out float tests in
+ ei_decode_SUITE and ei_encode_SUITE in
+ lib/erl_interface/test. Modify them to make them match
+ the style of other tests in the same suites.</p></item>
+ </list> <p>These changes are based on an ei float patch
+ from Serge Aleynikov originally submitted against R12B-2
+ in July 2008 and reworked by Steve Vinoski May 2010.</p>
