我们提出了除法和平方根算法的计算与更多的位比处理的浮点硬件。这些算法避免了将两个高精度数字相乘的需要，将最后一次迭代的速度提高了10倍。我们还展示了如何用相对较少的额外操作产生最接近精确结果的浮点数。
We present division and square root algorithm for calculations with more bits than are handled by the floating-point hardware. These algorithms avoid the need to multiply two high-precision numbers, speeding up the last iteration by as much as a factor of 10. We also show how to produce the floating-point number closest to the exact result with relatively few additional operations.
