Converting -190.25 to decimal, my first step is to change it to -191 + 0.75
0.75 = .11 in binary
191 = 010111111 in signed binary
-191 = 101000001 in signed binary using 2s complement (not sure about this part)
And adding together gives 101000001.11
However the answer given is 11101000001.110 and I have a couple of questions.
1) Why is the decimal represented in 11 bits? 2) Why is the 0 added at the 3rd decimal place?
I have been stuck a long time on this question and would really appreciate a step by step solution. Cheers.
