所表现出的最终数值舍入到小数三位。
The final numerical values, as displayed, were rounded off to three decimal places.
在许多情况下，舍入误差是可以控制的，即使在很复杂的计算，使得上部6 - 8位小数是正确的。
In many cases, the round-off error can be managed, even over really complex computations, such that the top 6-8 decimal places are correct.
8这样的补充，32位的类型会溢出，您将需要重新规范正确舍入和移位。
After 8 such additions, the 32-bit type would overflow and you would need to re-normalize by rounding and shifting right.
