+// 4/04/00  Unwind support added
+// 8/15/00  Bundle added after call to __libm_error_support to properly

+// Overview of operation
+//====================================================================
+//  fmod(a,b)=a-i*b,
+//  where i is an integer such that, if b!=0, 
+//  |i|<|a/b| and |a/b-i|<1
+
+// Algorithm
+//====================================================================
+// a). if |a|<|b|, return a
+// 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).
+
+// Special cases
+//====================================================================
+// b=+/-0: return NaN, call libm_error_support
+// a=+/-Inf, a=NaN or b=NaN: return NaN
+
+// Registers used
