+//====================================================================

+// b). get quotient and reciprocal overestimates accurate to 
+//     33 bits (q2,y2)
+// c). if the exponent difference (exponent(a)-exponent(b))
+//     is less than 32, truncate quotient to integer and
+//     finish in one iteration
+// d). if exponent(a)-exponent(b)>=32 (q2>=2^32)
+//     round quotient estimate to single precision (k=RN(q2)),
+//     calculate partial remainder (a'=a-k*b), 
+//     get quotient estimate (a'*y2), and repeat from c).
