The /ROUND_DECIMAL qualifier causes the compiler to round  packed  decimal
   numbers rather than truncate them.

   The format of the /ROUND_DECIMAL qualifier is as follows:

      /[NO]ROUND_DECIMAL

   The /NOROUND_DECIMAL qualifier causes  the  compiler  to  truncate  packed
   decimal numbers rather than round them.

   The default is /NOROUND_DECIMAL.
