Not that I can see.  Neither the Floating Constants section in LEXICAL
ELEMENTS nor the runtime specification of library routines like fscanf
say anything about internal representations.  The MetaWare compiler we
use generates IEEE +0.0 (0x00000000) for the string "0.0" and IEEE
-0.0 (0x80000000) for the string "-0.0".
