True or false: A signed data type has an equal number of non-zero positive and negative values available. R&H says true, I say false. Seems to me: byte range is -2^7 to 2^7 - 1 So there's 127 different pos values and 128 different neg values. There are more neg. then pos. Am I missing something here?

Are you sure they give the answer as TRUE. I thought I remembered in the 2nd edition that this question was in chapter 1 and it was false. But I could be mistaken. In any event, you are correct. Bill
