...decimal — 10, etc. Hence to find the characteristic of the logarithm of a number less than 1, subtract the number of ciphers between the decimal point and the first significant figure from 9, writing — 10 afler the mantissa. Thus, log .000431 = 6 + the mantissa - 10. 8. The two integral...

...characteristic of the logarithm of a number less than unity is negative, and is numerically one greater than the number of ciphers between the decimal point and the first significant figure. EXPLANAT二ON OP THE TABLES. 丫 叉 Verify the following statements 山 肛 助 扣 n 乱 卜 oflog58392...

...characteristic when the latter is positive ; when the characteristic is negative the number is a decimal, and the number of ciphers between the decimal point and the first significant digit is one less than the figure in the characteristic. (See the rule for finding the characteristic.)...

...one less than the number of integral places ; for a decimal number it is negative and one more than the number of ciphers between the decimal point and the first significant figure. Thus, to find the logarithm of 254, a number containing 3 integral places, the index is 2, the decimal...

...less than the number of figures in the whole number. When the number consists of decimais only, count the number of ciphers between the decimal point and the first significant figure after it, and subtract this number from 9 : the remainder is the index. " " To find the natural number...

...is less than 1, the characteristic of its logarithm is negative, and is numerically 1 greater than the number of ciphers between the decimal point and the first significant figure. When the minus sign is written over the characteristic, it denotes that it alone is negative. Thus,...

...following rule : The characteristic of the logarithm of a number less than 1 is found by subtracting from 9 the number of ciphers between the decimal point and the first significant figure, writing a — 10 after the mantissa. 71. The mantissas of logarithms of numbers are given in tables...

...characteristic when the latter is positive ; when the characteristic is negative the number is a decimal, and the number of ciphers between the decimal point and the first significant digit is one less than the figure in the characteristic. (See the rule for finding the characteristic.)...

...in the whole number, and out less than i is o. (2.) When the number consists of decimals only, count the number of ciphers between the decimal point and the first significant* figure after it, and subtract this number from 9 ; the remainder is the index. Ex. 1. Find the log. of '0058...

...there are 13 additional figures before the decimal point is reached. The numbers in parentheses denote the number? of ciphers between the decimal point and the first significant figure: for example, in e~°° there are 21 ciphers between the decimal point and the figures 192874985. Auxiliary...
