0435.  What will be the range of the characteristic of the exponent given the traditional 7-bits allocated to it? What does this mean?

 

Since 27 = 128, we can have 128 different values associated with the characteristic. However, the characteristic can take-on both negative and non-negative values, the range would be:

 

-26 to +26 – 1 or -64 to 63

 

This means that we can move the decimal place 63 positions to the right, or 64 positions to the right. In other words, the we could represent such numbers as:

 

0.123E63 =

123000000000000000000000000000000000000000000000000000000000000

 

or

 

0.123E-64 =

0.0000000000000000000000000000000000000000000000000000000000000123
