CPT4 - Exponents

Just reading through my book and it says:

If the exponent is negative (indicated by a 1 in its leftmost bit), the binary point is moved left instead of right.

And then it goes onto saying an exponent of 111110 is -2.

Why is it -2??

oooooooooooooh

thats hard

:confused:

:confused:

well i did binary stuff back in year 10 and did it in AS

we just learnt the basics though

if it has a 1 as the most significant bit then it is negative, to find out the magnitude, compliment it, so its:
000001
and then add one, which makes it 000010, which is 2.

OP

Ohhh!

*flicks a few pages back*

I see, shows how to convert negative denary to binary.
