...in the number. 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, since 10s = 1000 and 104 = 10,000, it is evident that log 7250 lies between... | |

...on. Hence, we have the general rule: The characteristic of the logarithm of a number between 1 and 0 is negative and numerically one greater than the number...the decimal point and the first significant figure. Thus, the characteristic of log.0345 is -2 ; of log.000479 is -4 ; and so on. 118. Mantissa of a common... | |

...LAW OF THE CHARACTERISTIC. All positive numbers less than 1 have a negative characteristic, and it is numerically one greater than the number of zeros between...the decimal point and the first significant figure. Thus log .000468 = 4.67025 log .175 = Ï.24304. 3. Mantissa not affected by change of decimal point.... | |

...one, c equals the number of integral figures in N, minus one. If N is less than one, c equals 9 minus the number of zeros between the decimal point and the first significant figure, minus 10 (the — 10 being written after the mantissa). (e) Mantissa or decimal part (m) of the common... | |

...fraction. For reasons given later, the characteristic of the logarithm of a decimal fraction is one more than the number of zeros between the decimal point and the first significant figure. Hence the logarithm of a number between 0.001 and 0.01 lies between — 3 and — 2, and is therefore... | |
