Problem #6  (Conversions)

Given the following base 10 decimals

a)3.75

b)0.7

c)89.9

1) Convert to binary, octal and hex, then 

2) Convert to Hex float with first 24 bits representing the

signed fraction and the last 8 bits representing the

signed exponent. Scaled as 0.FRACTION x 2^EXPONENT

3) convert a) to scaled integer binary 1 unsinged byte maxium bits,

   convert b) to scaled integer binary 2 unsinged byte maxium bits,

   convert c) to scaled integer binary 3 unsinged byte maxium bits,

4) multiply 3) by 1 byte value 7 then shift back to integer and output the result

5) Then convert using IEEE 754 format
