When log
n has been expressed as p + log m, where p is an integer and 0 log m < 1, we say that p is the
“characteristic” of log n and that log m is the “mantissa of log n Note that characteristic is always an
integer – positive, negative or zero, and mantissa is never negative and is always less than 1 If we can
find the characteristics and the mantissa of log n, we have to just add them to get log n Thus to find log n, all we have to do is as follows:
