...the given number is less than 1, the characteristic of the logarithm is negative and is one unit more than the number of zeros between the decimal point and the first significant figure of the number. Thus, the characteristic of log 2.8 is 0 ; the characteristic of log 4562.76 is 3 ;...

...the decimal point ; when the number is less than 1, the characteristic is negative, and is one more than the number of zeros between the decimal point and the first significant figure. The first three figures of a number of four figures are found in the left-hand column marked N; the...

...and so on. Hence, the characteristic of a decimal fraction is negative, and is numerically one more than the number of zeros between the decimal point and the first significant figure. There are two ways in common use for writing the characteristic of a decimal fraction. Thus, (1) log...

...a number greater than 1 is one less than the number of digits to the left of the decimal point. II. The characteristic of a number less than 1 is negative...the decimal point and the first significant figure. Accordingly the characteristic of 25 is 1 ; of 2536 is 3 ; of 6 is 0; of .4 is - 1 ; of .032 is - 2...

...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 2 Give the characteristic of : 1....

...remembered that if T is expressed as the fractional part of unity the characteristic is equal to minus the number of zeros between the decimal point and the first significant figure. Thus, the characteristic of T = 0.5 is 0; that of T = 0.005 (0.5 per cent) is — 2 ; etc. EXAMPLE...

...point. If the number is less than 1, the characteristic of its 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. Conversely, if the characteristic of a given logarithm is positive, make the number...

...characteristic of the common logarithm of a number less than 1 is negative ; numerically it is one more than the number of zeros between the decimal point and the first significant figure. Thus, the characteristic of log .0045 té — 3 ; of log .00027, is — 4. EXERCISE 173 What are the...

...characteristic of the common logarithm of a number lees than 1 is negative ; numerically it is one more than the number of zeros between the decimal point and the first significant figure. Thus, the characteristic of log .0045 is — 3 ; of log .00027, is — 4. EXERCISE 86 "What are the...

...= 4 + 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. For example, log 0.03 = — 2 + some mantissa, and log 0.00076 = — 4 + some mantissa....
