Describe the internal format for single-precision IEEE floating
point values.


What is normalization?  Hidden bit operation?


Why is the stored exponent in biased/excess notation of the real exponent?


Convert the following decimal values to single-precision IEEE floating
point representation (expressed in hex) showing the binary fixed-point
intermediate value __________ x 2^0.

-99.125				0xC2C64000
-1.5				0xBFC00000
0.5				    0x3F000000
