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。
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.
您可以使用函数abs和arg获得绝对值和辐角。
You can use the functions abs and arg to obtain the absolute value and the argument.
基于进入系统的时间，写操作具有幂等性(不管操作多少次结果都不变的性质，比如取绝对值的函数就具有幂等性)和交换性(操作顺序不影响结果，比如加法就具有交换性)。
Write operations are idempotent and commutative, based on the time they enter the system.
对读者来说，他应该知道绝对值不是绝对会出现的一些值，也不是某种有实用价值的函数。
A reader is expected to know that an absolute value is not about some value that happens to be absolute, nor is a function about anything functional.
