     33 //                     ---------------------
     34 //
     35 //   Assume x=2^{3*k+j} * 1.b1 b2 ... b5 b6 ... b52, where j = 0,1,2.
     36 //   Let r=(x*2^{-3k-j} - 1.b1 b2 ... b5 1)* rcp[b1 b2 ..b5],
     37 //   where rcp[b1 b2 .. b5]=1/(1.b1 b2 b3 b4 b5 1) in double precision
     38 //   cbrt(2^j * 1. b1 b2 .. b5 1) is approximated as T[j][b1..b5]+D[j][b1..b5]
     39 //   (T stores the high 53 bits, D stores the low order bits)
     40 //   Result=2^k*T+(2^k*T*r)*P+2^k*D
     41 //   where P=p1+p2*r+..+p8*r^7
     42 //
     43 // Special cases:
     44 //  cbrt(NaN) = quiet NaN, and raise invalid exception
     45 //  cbrt(INF) = that INF
     46 //  cbrt(+/-0) = +/-0
     47 //
