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）

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)

一些处理器在处理无符号整型数要比处理符号整型数快得多，这也是一个好的习惯，有利于代码的自我文档化(self - documenting)。

Some processors can handle unsigned integer arithmetic considerably faster than signed (this is also good practice, and helps make for self-documenting code).
