1. Given A = (1111 0011 1100 0011 1100 0000 0000 0000)2 and assuming A is a single precision IEEE-754 floating point number, what decimal value does A represent? Show A in normalized scientific notation: 1.X * 2Y.

2. Convert (28.4)10 to IEEE-754 single-precision binary.

3. Given X = (0100 0010 0000 1111 0000 0000 0000 0000)2 and Y = (0100 0001 1010 0100 0000 0000 0000 0000)2 in single precision IEEE-754 floating point numbers, perform the following operations. Show all of your work and express the final answer in single precision IEEE 754-floating point representation.

1. X+Y

2.X*Y

Hint: show each value in binary normalized scientific notation prior to performing the arithmetic. This should make following the algorithms easier.
