Decimal to binary conversion question

[Zanix]

How do you convert fractions or something like 0.0099 decimal into binary?



I've got it figured out, like 16 decimal is like 10000 binary, but what about #s >0 and <1?



HOT BABE!!!

Ok, ok... here's one that a little better

... 2^2 + 2^ 1 + 2^0 + 2^-1 + 2^-2 + 2^-3 ...
the decimal point is between the 0 and -1 exponents

so, .5 or 1/2 base ten is .1 in binary
.75 or 3/4 is .11 (2^-1 + 2^-2)
thats the gist, hope not too confusing

for other, not so nice conversions you gotta think about infinite geometric series and stuff that im not too fresh on

seeing as how you are pondering about binary conversions, i am guessing that is the best pic you could get.....

thx for the link, but I couldn't find one that handles 0.** stuff at all..

Just learn floating point.

ok... So, I'm thinking 0.1 binary = .5 dec, so 0.01 bin = 0.25 dec, so that 0.11 bin = 0.75 bin, right? (.25 + .50)

So then, 0.001 bin = 0.125 dec?


The hw question I'm trying to answer is:

16.625 dec = _______ bin


I'm thinking 10000.101



Is that right?



thx for the help btw

:thumbsup:

16 = 10000
0.625 = 0.5 + ___ + 0.125 = .101

16 - 8 - 4 -2 - 1 - .5 - .25 - .125 - .0675 - etc, no?

More of the new babe, please.

Example: Convert 0.8 to Binary


0.8 <---
x 2
-----
1.6
x 2
-----
1.2
x 2
-----
0.4
x 2
-----
0.8 <---


0.8 base 10 is equivalent to 1100 base 2

Perhaps not the best way, but very simple to follow.

Sorry for the crummy formatting. Forum formatting won't let me use more then one space.
