The signed division will take more time to execute because it rounds towards zero, while a shift rounds towards minus infinity.

有符号的除法要耗费更多的时间，因为除法是使最终结果趋向于零的，而移位则是趋向于负无穷。

Because filenum will always be less than filecount, the integer division filenum/filecount will always produce zero, so each iteration of the loop will echo

由于 filenum 始终小于 filecount，整数除法 filenum/filecount 将始终生成 0，因此每次迭代循环都将生成

To avoid any division by zero or overflow, transform all division into multiplication and check for the sign (horizontal lines with Y2=Y1 do not count in the algorithm)

要避免任何数与 0 相除或溢出，将所有除法转换为乘法并检查运算符号（Y2=Y1 的水平线不会计入算法）
