95 * dt is cbrtl(x) to ~47 bits (after x has been reduced to 1 <= x < 8).
99 t = dt + (0x1.0p32L + 0x1.0p-31L) - 0x1.0p32;
102 * Round dt away from zero to 47 bits. Since we don't trust the 47,
104 * might be avoidable in this case, since on most machines dt will
107 * dt is much more accurate than needed.
109 t = dt + 0x2.0p-46 + 0x1.0p60L - 0x1.0p60;
