Example:1 1259.125 Decimal number representing in Single & Double Precision Floating point representation

[mayeesha_farjana]

1st correction: 10011100011 is not the binary representation of 1259. It is the binary representation of 1251 actually. Now, let's assume the number is 1251.125, then the single precision format would be 0(sign bit as +ve number) 10001001(8 bit exponent) bit Mantissa---here we need to take the whole N as Mantissa, even after that if there are not 23 bits, then we have to add 0s to the right as padding 0 to the right doesn't change the value of a floating point number. Thank you. <3

[md.jasimuddin]

this will be the correct division, 1259=10011101011

[aryanarya]

In step 3, the mantissa is missing the last 3 digits of the number and also mantissa alone should be 23 bits.

[pasanmanahara]

madam your theory was very good. but (1259 dividing by 2 ) this equation in your video i think its incorrect... because 629/2 is 314 .not 312... other theory part very good.

[thejaswinichapiri]

Mam you forget about adding at last 001 in mantissa i.e., step-3 and step-4

[yogeshrajbanshii]

i think nobody viewed the mistake in binary convertion of 629 ie. 314 in place of 312

[sharansingh]

I though it's 23 bits but only in mantissa. Meanwhile, she counted the bits as 23 altogether.

My exam is at 9:00AM in the morning & now I'm watching it at 2:20AM .. Please wish me a good luck 🙂

Hi mam... I didn't understand the last one in mantissa..U said u have to fill upto 32 bits but U r adding 0's upto 23 bits...the total digits there are only 23 ..Should we add upto 32 bits mam... ?? Plzz clear this mam

Normalize the floating point number -8-625x10² and represent it in IEEE 754 single format.

Thank you mam.Your explanation is very nice

[suprisinglifefacts]

Am glad to see these reactions, this means that your pupils are following madam 👍

1259=(10011101011.001) base2
Mantissa is wrong....,
we put the final Mantissa in that box after normalisation so it should be

[tusharwalia]

629/2=314 and 1 remainder. The question is solved w.r.t 1251.125.

[saikomaladdagalla]

There's a error in the decimal to binary conversion part of 1259, because of this error my friend questioned his entire existence.

[shibnak]

Mam how can we represent the negative number....is the same method...or need to take the compliment?

[NotXGaming]

You interchanged the position of Mantiss and exponent, mantisa should be 23 bits, and exponent 8 bits

[abhinandansaini]

mam your binary representation for 1259 is wrong
the correct is (10011101011)2
thankyou

[ruchiratabassum]

very well explained just with a little error, thanks a lot.

[PrinceKanhya]

Mam please correct the division from 629 to 312. It should be 629 to 314 and so on
