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

...following rule is used -for determining the characteristic of the logarithm of a decimal fraction: Take the number of zeros between the decimal point and the first significant figure, subtract lt from 9, and annex - 10 after the mantissa. EXERCISE 111 Give the characteristic...

...point in the antilogarithm. Rule 4. — If the character is negative, the number is less than one, and the number of zeros between the decimal point and the first significant figure is one less than the number representing the negative characteristic. Example. — The antilogarithm...

...right of minus three. Hence, as before, the characteristic here is negative and numerically 1 more than the number of zeros between the decimal point and the first significant figure. This statement, which is true in all cases mentioned above, can be proved for the characteristic...

...If the number is less than 1, the characteristic of the logarithm is negative and one unit more than the number of zeros between the decimal point and the first significant figure of the given number. Table II. Reciprocals. — If the reciprocal of 4.68 is desired, locate...

...characteristic of a decimal fraction is always negative, and it is numerically equal to one more than the number of zeros between the decimal point and the first significant figure of the decimal. The characteristic is minus this number. Thus log 0.862 has the characteristic...

...log N is n — 1. If the number N is less than 1 the characteristic is negative and one greater than the number of zeros between the decimal point and the first significant figure in N. From the preceding paragraphs we see that the mantissa of log N is log N' where N' is...

...point; while the characteristic for 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. sequence of digits. A more accurate method will be shown in section 7, where linear interpolation...
