Again assuming 9-bit two's complement binary representation, find the hex shorthand for the bit pattern that represents the decimal number -73. (Your answer should be precisely 3 characters long.)

Assuming a three-bit exponent field and a four-bit significand, write the bit pattern that would be used for the decimal value 0.42. (Your final answer should be 8 bits without any spaces between.) (Note: take care to round correctly when the significand digits don't all fit into the 4-bit cell!)

Assuming a three-bit exponent field and a four-bit significand, what decimal value is represented by the bit pattern 11010110?

For IEEE single-precision floating point, what is the number whose bits are represented by the hexadecimal code B350 0000. (Write your answer precisely using normalized scientific notation as "X*2^(Y)", without spaces between), where X is expressed in binary possibly a minus sign in front of it, and the exponent Y is written as a decimal integer.)
