To quote from
http://docs.oracle.com/cd/E19060-01/stud8.compiler/817-0932/ncg_goldberg.html:

“Of course, this form of double-rounding is highly unlikely to affect any
practical program adversely.”

Therefore, rather than retard the precision of all programs, I suggest creating
two standard functions,

   double roundToDouble(real x);
   float roundToFloat(real x);

which will guarantee a result rounded to the return type precision.
