...The characteristic of the logarithm of a number less than 1 is negative, and is numerically one more than the number of ciphers between the decimal point and the first significant figure in the given number. These rules are very important and should be thoroughly memorized-,/ EXAMPLES...

...point. (2) If 0 < N < 1, the characteristic of log N is negative and may be obtained as follows: Count the number of ciphers between the decimal point and the first significant digit, subtract this number from 9, write the remainder as a positive characteristic and annex —...

...Log 1.359 = 0.13322 b. For numbers less than unity, the characteristic is negative. It is one more than the number of ciphers between the decimal point and the first significant figure. Since the mantissa is positive, the negative sign is placed above the characteristic to show...
