CDA3101 Quiz 1 Last Name ________________________ Spring 2007 First Name ________________________ Time: 10 minutes Show all your work to get full credits. 1. Consider an 8-bit floating point number representation that uses 1 bit for the sign, 3 bits for the biased exponent and 4 bits for the fraction (f). Other than the numbers of bits, the representation is similar to the IEEE 754 standard. a. (5 points) What decimal value does the following bit pattern represents?

Unformatted text preview: 11001100 (-1) S x (1.f) x (2 BiasedExponent-Bias ) = (-1) 1 x (1.75) x (2 4-3 ) = -3.5 10 b. (5 points) Show the bit pattern that represents the value 5.5 10 in the above described representation. 5.5 10 = (101 .1) 2 = 1.011 x 2 2 (after normalization) S = 0, Biased Exponent = 2+3 = 5 10 =101 2 , Fraction(f) = 011 2 Final bit pattern will be: 0 101 0110...
