In case someone is wondering why there is a need to use bias. It is to make fast magnitude comparison of floating point numbers possible in hardware. By using a bias we are effectively avoiding the need to store the exponent as negative numbers. If we had allowed the exponent to be stored as negative number (probably as a 2's complement), then during the occasion when there is a need to compare two exponents of two FP numbers, we need to obtain the magnitude of the 2's complement representation of the exponent by performing the 2's complement (need CPU cycles) operation (this is how you obtain the magnitude of a negative number represented in 2's complement form. If the number was represented in sign magnitude form, bits other than the sign bit would have directly given the magnitude) So if there is a bias, we can just forget about the negatives and just compare the bits of two exponents and say which one is larger.

@stevenpetryk6869

No, you’re right. 0.125 is represented as 0.001 in binary (2^-3 = 1/8). You’ll notice that if you continued you’d just get more and more zeroes: 0.50 * 2 = 1 0 * 2 = 0 0 * 2 = 0 Which is the same as just adding more zeroes to any decimal number’s decimal side: like how 10 = 10.0000 (ignoring precision, which computers don’t usually encode ). So your number in binary is (I think-doing the math on my phone right now): 1 1100 0110.001

@@rickthebrick12 If you're going from paper -> electricity, you add 127. If you're going from electricity -> paper, you subtract. For a mathematical exponent of 3, the bits in the register would be 3 + 127 = 10000010₂.

If Paper (decimal) to Ieee , then map ur math into this 1.M * 2^(E-127). Evaluate M and E , later arrange them as S E M. That’s it

Shouldn't the exponent have the value 6
my number is 454.125 and when i started converting the second part (0.125) it stopped at a whole 1 so it went like this: 0.125 * 2= 0.25 0.25 * 2=0.50 0.50 * 2=1 did I do it wrong?

No, you’re right. 0.125 is represented as 0.001 in binary (2^-3 = 1/8). You’ll notice that if you continued you’d just get more and more zeroes: 0.50 * 2 = 1 0 * 2 = 0 0 * 2 = 0 Which is the same as just adding more zeroes to any decimal number’s decimal side: like how 10 = 10.0000 (ignoring precision, which computers don’t usually encode ). So your number in binary is (I think-doing the math on my phone right now): 1 1100 0110.001

@@kareemashouri1429 if you Google “454 in binary” you’ll see that something went wrong with your conversion. I’d recommend trying again.
"If you were going to get 100 on this exam, you wouldn't be watching this video" way to be discouraging lol

Don’t take it too seriously! I made this video to help my students get 100’s :)
why you repeated that loop of binary fraction representation at the matisse case , normally you should complete the mantisse result by zeros !!
