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
