 9.49.3 Vax Machine Directives
 -----------------------------
 
 The Vax version of the assembler supports four directives for generating
 Vax floating point constants.  They are described in the table below.
 
 '.dfloat'
      This expects zero or more flonums, separated by commas, and
      assembles Vax 'd' format 64-bit floating point constants.
 
 '.ffloat'
      This expects zero or more flonums, separated by commas, and
      assembles Vax 'f' format 32-bit floating point constants.
 
 '.gfloat'
      This expects zero or more flonums, separated by commas, and
      assembles Vax 'g' format 64-bit floating point constants.
 
 '.hfloat'
      This expects zero or more flonums, separated by commas, and
      assembles Vax 'h' format 128-bit floating point constants.
