/ROUNDING_MODE

    /ROUNDING_MODE=option
    /ROUNDING_MODE=NEAREST (D)

 For /FLOAT=IEEE_MODE, the /ROUNDING_MODE qualifier lets you select
 one of the following IEEE rounding modes:

  o  NEAREST (default)

  o  DYNAMIC

  o  MINUS_INFINITY

  o  CHOPPED


 For /FLOAT=G_FLOAT or /FLOAT=D_FLOAT, rounding defaults to
 /ROUNDING_MODE=NEAREST, with no other choice of rounding mode.
