bitwise NOT

The bitwise EXCLUSIVE OR, or XOR (^), produces a one in the output bit if one or the other input bit is a one, but not both.

若两个输入位的某一个是1，但不全都是1，那么按位XOR（^，异或）在输出位里生成一个1。

The next and last UDF to cover bitwise operations is bitwise NOT that performs a bitwise logical NOT operation for one given integer value as translated to a binary expression.

下一个也是最后一个涉及逐位运算的UDF是逐位NOT运算，在转换成二进制表达式时，该UDF对给定的整数值执行逐位逻辑NOT运算。

For booleans the bitwise operators have the same effect as the logical operators except that they do not short circuit.

对于布尔值，按位运算符具有与逻辑运算符相同的效果，只是它们不会中途短路。

This allows you to perform bitwise logical AND, OR, XOR, and NOT comparisons.

这样便可以执行逐位的逻辑AND、OR、XOR和NOT比较。

Spu_eqv is a bitwise equivalency operation, not a per-element equivalency operation.

spu eqv是针对位的相等操作，而不是针对每个元素的相等操作。

Bitwise operations perform logical AND, OR, EXLUSIVE OR, and NOT operations on binary representations of their integer arguments.

逐位运算在其二进制形式的整型变量上执行逻辑AND、OR、EXLUSIVE OR和NOT运算。

Now we need to provide bitwise operation functions:& ( and),' ( or),^ ( exclusive or), or~ ( not).

现在，我们需要提供逐位运算函数：&（and）、（or）、^（exclusive or）、or~（not）。
