[Glass] Floats problem with SIXX between Pharo and GemStone

[Masashi UMEZAWA]

Hi Mariano,

How about just defining:

SmallDouble >> sixxType
  ^'Float'

SmallDouble >> sixxWriteValue
  ^self asFloat

I'm not using GemStone right now, so maybe my assumption would be
inaccurate. But just a quick answer.

Regards,
