 9.39.4 Floating Point
 ---------------------
 
 The floating point formats generated by directives are these.
 
 '.float'
      'Single' precision (32-bit) floating point constants.
 
 '.double'
      If the '-m64bit-doubles' command-line option has been specified
      then then 'double' directive generates 'double' precision (64-bit)
      floating point constants, otherwise it generates 'single' precision
      (32-bit) floating point constants.  To force the generation of
      64-bit floating point constants used the 'dc.d' directive instead.
