Decimal number -5 represented as a halfword in Hexadecimal notation is? - Answers

Alright, let's forget the - for a while convert 5 to binary. do this: 5/2=2.5 2/2=1 1/2=0,5 than this: 2.5 absolute value=2 1 absolute value=1 0,5 absolute value=0 finally this 2*2=4 and 5-4=1 2*1=2 and 2-2=0 2*0=0 and 1-0=1 <--(last digit) = 101 complete the binary number by placing a 0= 0101. Now as you might know HW = 2 bytes and 1 byte is 8 bits so to to complete you should place 0000 0000 0000 before your result: 0000 0000 0000 0101 Let's not forget about the - though... you'll have to invert your result 0000 0000 0000 0101= 1111 1111 1111 1010 and increment it by 1=1111 1111 1111 1011 and there is your result... You could check your result this way: 0000 0000 0000 0101 +1111 1111 1111 1011 1 0000 0000 0000 0000 The first bit defines if your decimal has a + or - (1=- and 0=+) The rest is simple... (1111=F) (1111=F) (1111=F) (1011=B)=FFFB (hex HW)
