+   IEEE 1003.1 lround function.  IEEE specifies "round to the nearest 
+   integer value, rounding halfway cases away from zero, regardless of
+   the current rounding mode."  However PowerPC Architecture defines
+   "round to Nearest" as "Choose the best approximation. In case of a 
+   tie, choose the one that is even (least significant bit o).". 
+   So we pre-round using the V2.02 Floating Round to Integer Nearest
+   instruction before we use the Floating Convert to Integer Word with
+   round to zero instruction.  */
