...following rule is used for determining the characteristic of the logarithm of a decimal fraction : Take one more than the number of zeros between the decimal point and the first significant figure, subtract it from 10, and annex — 10 after the mantissa. EXERCISE 91 Give the characteristic of 1.... | |

...mantissa. 2. The characteristic of the logarithm of a number between 0 and 1 Is negative and is one greater than the number of zeros between the decimal point and the first significant figure in the number. For example, log 0.02 = — 2 + some mantissa, and log 0.00076 = — 4 + some mantissa.... | |

...the decimal point. The characteristic of a number less than 1 is negative and one greater numerically than the number of zeros between the decimal point and the first significant figure of the number.
