// 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
//
