+/* long [r3] lround (float x [fp1])
+   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 can't use the PowerPC "round to Nearest" mode. Instead we set
+   "round toward Zero" mode and round by adding +-0.5 before rounding
+   to the integer value.  */
