+//                     ALGORITHM DESCRIPTION
+//                     ---------------------
+//
+//   Assume x=2^{3*k+j} * 1.b1 b2 ... b5 b6 ... b52, where j = 0,1,2.
+//   Let r=(x*2^{-3k-j} - 1.b1 b2 ... b5 1)* rcp[b1 b2 ..b5],
+//   where rcp[b1 b2 .. b5]=1/(1.b1 b2 b3 b4 b5 1) in double precision
+//   cbrt(2^j * 1. b1 b2 .. b5 1) is approximated as T[j][b1..b5]+D[j][b1..b5]
+//   (T stores the high 53 bits, D stores the low order bits)
+//   Result=2^k*T+(2^k*T*r)*P+2^k*D
+//   where P=p1+p2*r+..+p8*r^7
+//
+// Special cases:
+//  cbrt(NaN) = quiet NaN, and raise invalid exception
+//  cbrt(INF) = that INF
+//  cbrt(+/-0) = +/-0
+//
