Assignment #5: 10 Points.

Due Date: Monday, 10/16/00.


(2)  1.	What range of decimal integers does .word allow in SAL?  
	Give the bit patterns in hexadecimal for the largest and 
	smallest (most negative) integers.

(2)  2. Show how SAL would store -27 (decimal) as a floating point 
	number.  Explain each of the fields that make up the floating 
	point representation.  Hint: Write a SAL program which 
	defines the constant.

(3)  3. Modify your factorial program from HW4, problem #3, to
        compute N! using floating point numbers.  N is a positive
	integer.**

        (a) What is the largest value of N for which N! is computed
            exactly?
        (b) What is the largest value of N for which N! is
            approximately correct?

        Explain your answers.

(3)  4. Write a SAL program which prompts for a decimal integer and
        prints it out in hexadecimal format.  Test your program on 1023
        and -32.**
