The properties of divisor sum function with cubic complement 关于立方幂补数除数和函数的性质
Negation of integral values is standard two s complement negation 整数值求反是标准的对2的补数求反。
Take the complement , or 得到补数,即
Negative category values appear as a complementary positive number in the event viewer 在事件查看器中,负类别值显示为正补数。
Perform an operation on one operand such as positive or negative , or on the complement 对一个操作数执行操作,例如正数、负数或补数。
Suppose you want to complement the three middle bits of a seven - bit string while leaving the other four bits undisturbed . what mask must you use together with what operation 假设你要将一个7位元字串的中间三个位元取补数,其他保留,你该用什麽样的遮罩及运算
The allowed number representations are two ' s - complement , one ' s - complement , and signed - magnitude . note that all of these number systems agree on the representation of positive numbers 允许的数字表示法是二补数,一补数,和符号量值.注意所有这些数字系统同意正数数字的表示
This standard allows one ' s complement , two ' s complement , or sign - magnitude number representations and arithmetic . arithmetic zero is represented as the value of a single cell with all bits clear 这个标准允许一补数、二补数或是符号式的量值和算术.算术零是以一个单一单元数值的所有位元都被清除来表示
