Represent (-456.1234) in Single precision & Double precision format. 9. Draw a flowchart for adding and subtracting two fixed point binary numbers where negative numbers are signed 1's complement presentation. 10. Explain IEEE-754 standard for floating point representation. Express (314.175) in all the IEEE-754 models. 11.A binary floating-point number has seven bits for a biased exponent. The constant used for the bias is 64. (a). List the biased representation of all exponents from -64 to +63. (b). Show that after addition of two biased exponents, it is necessary to subtract 64 in order to have a biased exponent's sum. (c). Show that after subtraction of two biased exponents, it is necessary to add 64 in order to have a biased exponent's difference.
