Assignment is due in on Thursday 18th October 2001
Binary Arithmetic
1. Convert the following numbers to binary using twos complement representation
9 -6 -99
2. Assuming 10 bits represent a binary number, with the first being a sign bit (twos
complement). Convert the following binary digits to decimal
000011101
001001011
110001111
3. Normalise the following numbers, which are held with a 10-bit mantissa and
6-bit exponent
0 000000110 000111
0 000010111 000110
1 111110111 000000
1 111111010 000011
4. the binary number 1010 1011 0111 can be represented in a number of different
ways
a. State its hexadecimal form
b. State its value in denary if it represents
(i) an unsigned binary digit
(ii) a twos complement floating point number with an eight bit mantissa
followed by a 4-bit exponent

1. Convert the following numbers to binary using twos complement
> representation
9 -6 -99
*** Ok convert them to binary, then invert all the bits (ie change the 1's to 0 and the 0 to 1's) then add 1 to the over all answer
example
take 4
4 in binary = 100
then make it 011
then add 1 100
and thats it.

ok the far left bit tells if it is positive or negative (1 = negative) take the other 9 bits and change them to decimal.
that should get you started and maybe make the others a little easier.

help would be much appreciated!
I could do it but that wouldn't help you in the slightest as if you are required to do it at a later stage then you might not be able to do it. I can give you help as how to attempt them and advise on easy ways to learn but i'll not do the exact questions.
