The only byte-oriented arithmetic function on the SPU is absdb, "absolute difference of bytes," which gives the absolute value of the difference between two operands.
SPU 上惟一一个面向字节的计算函数是absdb(意思是 “absolutedifferenceofbytes”),计算两个操作数间的差的绝对值。
You should make each different arithmetic function its own action/method/whatevertheframeworkcallsit and you should use the frameworks input validation for the form values (if it has one).
你需要为每一种运算设置单独的动作,或者说方法(每个框架的叫法不一样),而且还要用到框架中的表单验证功能(如果框架提供了这一功能的话)。
