r's complement
I have little confusion about r's complement. See the following examples: eg1) calculate F's compl. of (2BFD) is? Solution : here we are calculating as FFFF - 2BFD= D402. eg 2) Given that (E0B)16−(ABF)16=Y. The radix 8's compliment of Y is ? Solution: (EOB ... - N(as mentioned in example 1 ) (b) when we use (r-1)'s compl + 1 (as mentioned in above example 2 )?
