Assignment #2: 10 Points.

Due Date: Friday, 9/24/04.


(4) 1.	Perform the necessary conversions to fill in the blanks in
	the following table.  Indicate any repeating patterns of
	digits by drawing a line over the repeating pattern.

	BINARY                  DECIMAL               HEXADECIMAL

	________                __2.2__                 _______

	1010.010                _______                 _______

(2) 2.	Redo Problem 3, HW#1 using float (not double) variables to 
	calculate the value of N factorial (N!).  What is the largest 
	value of N for which N! is calculated exactly?  What is the 
	largest value of N for which N! is approximately correct 
	(sign and most significant digits correct)?  Explain.**

(1) 3.	Convert 0.6 to IEEE single precision floating point and give
	the result in hexadecimal.

(2) 4.	Write and test C (or C++) code to reverse the sign of a floating 
	point number WITHOUT using arithmetic.  Use only bitwise operations
	and test on both positive and negative floats.  Hint: This is a 
	one-liner!**

(1) 5.	What is the output from the following C++ conditional expression?  
	Explain your answer.

	(-1 < 0U) ? cout << "-1 < 0 is true!" : cout << "-1 < 0 is false!";


      **For full credit, turn in a well commented program listing,
	including your name and the problem number, and the results
	of the computer run for this problem.
