使用这种方法,对于具有32位尾数的两个浮点数相除,主要运算只是32次减法和32次移位,速度快,且能完全保留浮点数的32位精度。这种方法的源程序如下。此程序在作者设计的以80186为CPU的微机系统中调试通过。
Using this method, the division of the two floating-point numbers with a 32-bit mantissa results in only 32 subtractions and 32 shifts for the main operation, which is fast and retains the full 32-bit precision of the floating-point number. The source of this method is as follows. This program is designed by the author to 80186 for the CPU of the computer system debugging through.
