Computing Homework

[Camels]

The following hexadecimal numbers represent 16-bit two’s complement numbers: B13C, 7010, 1FFF, 8A1E, 9000, F73F. Can you tell which ones represent negative numbers?

B13C – 1011000100111100

7010 – 0111000000010000

1FFF – 0001111111111111

8A1E – 1000101000011110

9000 – 1001000000000000

F73F – 1111011111110011

I've got as far as that^ which may even be wrong, anyone know what I have to do next?

I think it's B13C, 8A1E, 900 and F73F but I can't remember how to do it.

i only just started doing the basics of this can't help :s

[Rick]

i've only learned computing language as far as neccessary for physics which wasn't a lot yet im sure there's some easy way to find your answer=]

you're right, negative binary numbers start with 1

so it's B13C, 8A1E, 900 and F73F

Cheers man ;D

12) Using one byte to hold each number, with an imaginary binary point fixed after the fourth digit, convert the following decimal numbers to binary:

a) 3.75

00111100

b) 5.1875

c) 7.562

d) 7.5627

Any ideas if a) is right? D:

I can perform a Google search, that's about as far as me and computers go. Sorry bud.

[DeltaPapa]

what the fuck lol

That actually makes sense?

[Sopuli]

dont understand shit about that :O

[Camels]

what the fuck lol

That actually makes sense?

It's binary.

[Realyo3]

lol only done basics of binary such as representing 2's complement etc

Hi Punjabian.
