Example #10 IEEE Floating Point Representation The format of a 64 -bit (double precision) floating point number ig : sign of fraction 1 bit biased exponent 11 bits fraction 52 bits The value of a double precision number is given by the following formula : s ign (biased _ exponent Ox3 FF) (-1) x 1. fraction x 2 A biased exponent in which all eleven bits are cleared is used to represent zero and denormal numbers, and a biased exponent in which all eleven bits are set is used to represent infinity and not-a-number. The format of a 32 -bit (single precision) floating point number is : sign of fraction 1 bit biased exponent 8 bits fraction 23 bits The value of a single precision number is given by the following formula: s ign (biased _ exponent - Ox 7 F ) (-1) x 1. fraction x 2 A biased exponent in which all eight bits are cleared is used to represent zero and denormal numbers, and a biased exponent in which all eight bits are set is used to represent infinity and not-a-number.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
