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)
这是乘法符号!
In this expression, we do not need a multiplication sign or parenthesis.
这个表达式中,我们不需要乘号或括号。
