Fixed Point Problems

1)
I assume these are the three base 10 representations expected:
two's complement: -9855
one's complement: -9854
signed magnitude: -22913
unsigned binary: 55681
And for a little added value:
fixed point: move the binary point from right to left for fixed point
	     rational number  (or integral number)
excess/bias: really anything one wants, given the right bias




2)
	in signed magnitude
	1) 100c00 exact
	2) 000e87 approximation because of truncation
	3) cannot be expressed because of overflow
	4) 000000 - underflow
	5) 840000 - underflow

3)
	in 2s complement
	1) cec9178d
	2) fffe4000
	3) 00010000
	4) fff8c000

Floating Point Problems

1)
	in hex:
	1) 43806000
	2) 3f6872b0
	3) c5801900
	4) 332bcc77
	5) c2800000

2)
	in hex:
	1) bfe00000
	2) 3f7fffff
	3) c0e80000

Extreme Issues

1)   0 cannot be expressed as   1.f x 2^e-127 for any e or f.

2)
	127  with e = Oxfe

3)
	-126 with e = Ox01

4)
	Two examples are the smallest and largest postive, denormalized 
	numbers:    Ox00000001
	            Ox007fffff
