Thanks for explaining in just over 4 minutes what my comp science lecturer failed to do in several hours.

You explain to me in 4 minutes what my professor failed in an hour. Thank you!

Good explanation, but you really should've chosen a better example that has values behind the decimal rather than an integer 9.

+Carlos Serrano well, when you convert back to decimal, you will always have to add that 1 because when you are converting FROM again FROM Decimal to IEEE 754 binary, you just remove 1.(you only care about fraction) and if you look at 2:20 , he got that number from pink highlight, that was considered a fraction because it is separated from other exponent and sign number... sorry for late response.

Thank you so much, keep it up with the good work :)

Forget it, I understood now... ThankYou Very helpful

damn, Quick and straight. Great tutorial

What could happen in the case of having floating points.. i mean... if the aswer is somthing like -9.35 or -35.25 ???? ?? sos!

thaaaaaaaaaaaank you so much I spent a lot time on KZread to understand, finally i understannnd

Great video thanks for posting. I have a mid-term today, and its helping with my studies. :-D

i'm being deadass all of the comments saying you explained in four minutes what my professor tried to in multiple hours is 100% sure. thank you

really nice example. cheers :)

please give us an example using a number that isn't an integer!

how would you go about converting to double precision (64 bits)? would you proceed the same way and just fill in the extra slots in the exponent and mantissa with 0's?

When the number is negative and it is in two's complement, do i have to calculate the absolute value of this number first, or is it ok to put only the 1 at the beginning of ieee754?

Thank you so much. You saved me.

Thank you so munch my brother ♥

What if there are 1s in the significand? We wouldn't just ignore them like we do if the rest were zeros right?

great explanation

i liked this example. i was confusing. thanks for help me.

Hello, please how did you come up with 127 and P as 3? would really appreciate the response. Thank you.

thank you good explanation awesome

So I am assuming the spaces are part of the notation? otherwise 100000 or 1000001 and many other things can be the exponent? edit: nvm, I just realize the exponent have to occupy 8 bits even if its 0000 0000

i got a question the value of the exp. is always 8 no matter what????

how does 127 + power came?

What if the exponent is 00000000 Would that mean that exponent = bias + p => 0 = 127 + p => p = -127 ??

Thank you..very well explained :)

good job!

Can someone explain to me why it's a 1 in 2:42? I thought it has to be 0 as it's a positive binary number.

what do you do if there are still values after the decimal after moving it??

You probably figured this out. But in case someone else was confused...consider what .1 means in base 10. It's in the 10^-1 position ( the 1/10th position). 1*(1/10)=1/10=.1 It works the same way in base 2. .1 in base 2 is 1*2^-1=1/2=.5. In base 2, the places to the right of the decimal place are 1/2, 1/4, 1/8, 1/16, ... and so on. .111 in base 2 is, in base 10, 1/2+1/4+1/8=(4+2+1)/8=7/8=.875. Just remember that for all bases, the places of the number are the powers of the base. In base 10, we have ... 10^3, 10^2, 10^1, 10^0, 10^-1, 10^-2, ... ( 1000, 100, 10, 1, 1/10, 1/100). In base 2, we have ...2^3, 2^2, 2^1, 2^0, 2^-1, 2^-2 ( 8, 4, 2, 1, .5, .25).

@xXGuitarFrom71Xx

9 жыл бұрын

Josh Oduyoye I think if you get a negative p that means you must shift your point leftwards. Imagine you ave, like in the example, 1.001... (adding that 1, as the uploader said), you would just shift the point to the left, and the result will be 0.1001... That in terms of computers is a non-normalized number, because its integer part is 0...

@duskshadow25

1000 0010 = 128 + 2 = 130. Remember that it's in base of 2. That's an 8 bit, so it goes from right to left 2^0, 2^1, 2^2, 2^3, 2^4, 2^5, 2^6, 2^7. Because the first four numbers are 1000, we know that is 2^7 (128). The second 4 numbers are 0010, which we know that is 2^1 (2). Remember that we ignore the 0. Therefore, 128 + 2 = 130

This video is so simple some steps just doesn't make sense without explanation. Like how did he get 127 for bias? And why the p = 3 isn't brought into the next equations? SMH

how did you get bias = 127?

@duskshadow25

8 жыл бұрын

Whatever you get for the exponent part, you will always use that number to subtract 127 because in 8 bits the highest is 127 since it's from 0 to 127. In this case, if you have 1000|0010 = 128 + 2 = 130. Use 130 - 127 = 3. The idea of 127 is the same as adding a 1 in front of the fraction portion. It'll always be 1.###.... except in this case you will always subtract 127 because that's the highest it goes in 8 bits.

I watched the vid a few times and still don't know whats he doing :(

suppose no. given was : 010000000 11000000 0000 0000 0000 0000 then as per my calculations P=1 ..., so in 1.1100000..... i shifted one decimal which gives me 11.100000..... so deciaml representation of (11) is 3 but answer is given 3.5

@viniciustinoco5261

6 жыл бұрын

I know it is too late for you but for new person ... The answer is, to the left of "." you will have 2^-1, 2^-2 ... so you have 11 (equals 3) + 2^-1 (equal 0.5). The final result is 3.5.
