great example would be nice if you could show case overflow and underflow

This video gives me life. Also yeah over/underflow examples would be cool af

Straight and to the floating point :) Great video!

lovely comment!!!

Thank you so much! It makes complete sense now.

Thanks, this video has saved me 5 marks in my exams which i sit in about 3 hours haha

can you do this, with a negative floating point? I'm having trouble understanding how that would impact the exponent

You add a negative number. As in, you do a substraction instead.

Thank you for this video! You saved my cosc Grade!

Dam i wish I found your channel before I took my midterm

Thank you for the perfect explanation!

Steven Petryk, Great video. So adding the values basically involves XORing the corresponding bits in each value. However I did wonder how one might go about adding values of differing bit lengths, is it sufficient to just pad the smaller of the values with zeros to force the bit lengths to match?

You literally saved my ass! Thank you so much!

This was SO USEFUL THANK YOU SO MUCH

bro u a lifesaver

My english sucks and I understood it. Great job man!

Good job m8, Greetings from China.

nicly explined....thanks sir

how do you know whether the answer is gonna be positive (0) or negative (1)?

how did you get the x mantissa? do we always add a 1 in front of the 0?

for normalized yes but not for denormalized

Thank you^^

Thank you!

You are awesome

How do we know when the result is positive or negative ?? Don't we see if we have 1 so It's negative and when we have 0 It's positive???

@Pavan Kumar what if we have the sum of two numbers that have the same exponent but one is positive and the other is negative? how you're gonne proceed?

What bout multiplication!! thank you so much

great it's very helpfull, can you make turtorial how to multiply it please.....

Why do we ignore the 1 in the left side of the decimal?

Thank you! That Video helped me a lot. Greetings from Germany

very good video thank you

Thats a long ass time ago but id love a vid for opposite key signature:((

well explained

Thank you

When you performed the binary addition you mentioned the answer was positive. Did you determine that the answer to the binary addition was positive because there was no overflow? If there was an overflow than that means the answer would have been negative right?

I have the same question, but since he used two positive numbers to begin with the answer has to be positive in this case...

Love you

thanks a lot

Helped me a lot. Thank you! Greetings from Germany.

cheers m8

thank you

Do you need to substract the 127?

maybe you can show an example with most steps involved... e.g. the sum with rounding steps is not normalized and needs normalization.. etc.

If it is always 1.(mantissa) * 2^(exponent) Then how do you represent zero?

@stevenpetryk6869

It's a special case-there's both a positive 0 and a negative 0 (sometimes you may see "-0" in JavaScript and other languages that use IEEE-754). -0 is represented as 1 0000 0000 000... +0 is 0 0000 0000 000... You can read more here! en.wikipedia.org/wiki/Signed_zero

The first (most significant) bit in the representation of the input numbers, in the video, x and y have a highest bit of 0, meaning they're both positive. 1 would indicate a negative floating point number.

@@richardbernard9873 Hi I know this is pretty old but maybe you can still answer my question. I know that the first bit indicates if the number is positive or negative but how do I calculate it when I add a negative number to a postive?

What do you do if one of the operands is negative? Add the two's complement instead of the negative number?

in the end, how do you know the sign-bit?

I understand the rest of the addition process and also that I Would have to normalise my sum in the end if it was sth like 0, 001 01 * 2^5 it becomes 1,01*2^2. I got that wrong, my question was kind of stupid. I am just confused how to do a subtraction. I would need to make some kind of twoscomplement?

Toni Cleaveland in this case you do a two's compliment on B, and add result to A. The idea here is that it's easier to add negative numbers than to subtract positive ones.
