I've started doing two's complementary and I wanted to check these answers, and I don't think their right. Any help is appreciated greatly.


The question:

The binary pattern 010000001110 can be interpreted in a number of different ways>

A) convert to hex - 40E

B) state its value as a decimal number if it represents a signed binary integer using two's complement representation - I got -64.875

C) state its value as a decimal number if it represents an unsigned fixed point number with four bits after the binary point - I got 64.875

If you could tell me if I've these right or wrong that would be a great help, and if you do decide to help me (your good people so you will) then working's would further help.

Thanks.
