+// float remainderf(float,float);
+//
+// Overview of operation
+//====================================================================
+// remainder(a,b)=a-i*b,
+// where i is an integer such that, if b!=0 and a is finite,
+// |a/b-i|<=1/2. If |a/b-i|=1/2, i is even.
+//
+// Algorithm
+//====================================================================
+// a). eliminate special cases
+// b). if |a/b|<0.25 (first quotient estimate), return a
+// c). use single precision divide algorithm to get quotient q
+// rounded to 24 bits of precision
+// d). calculate partial remainders (using both q and q-ulp);
+// select one and RZ(a/b) based on the sign of |a|-|b|*q
+// e). if the exponent difference (exponent(a)-exponent(b))
+// is less than 24 (quotient estimate<2^{24}-2), use RZ(a/b)
+// and sticky bits to round to integer; exit loop and
+// calculate final remainder
+// f). if exponent(a)-exponent(b)>=24, select new value of a as
+// the partial remainder calculated using RZ(a/b);
+// repeat from c).
+//
+// Special cases
+//====================================================================
+// a=+/- Inf, or b=+/-0: return NaN, call libm_error_support
+// a=NaN or b=NaN: return NaN
+
+#include "libm_support.h"
+
+//
+// Registers used
+//====================================================================
+// Predicate registers: p6-p12
