...respectively the characteristic and mantissa of the logarithm. From the above illustration it is evident that the characteristic of the logarithm of a number greater than unity is one less than the number of figures to the left of the decimal point in the number, and that the characteristic of a number less...

...therefore a mantissa table. 362. How the Characteristic is Determined. 1. NUMBER GREATER THAN UNITY. The characteristic of the logarithm of a number greater than unity is 1 less than the number of integral figures in the number. Thus log 8628 = 3.+ log 86.28 = 1.+ log 508.3...

...point is 1, and of a number having three digits to the left of the decimal point is 2. In general, The characteristic of the logarithm of a number greater than unity is 1 less than the number of digits to the left of the decimal point . (b) When the given number is a...

...called its characteristic, and the decimal part its mantissa. The characteristic of the logarithms of a number greater than unity is one less than the number of digits at the lefl of the decimal point. ORAL EXERCISES 1-12. State the characteristic and the mantissa...

...change the decimal part, the mantissa, of the logarithm. 636. Characteristic Law. The characteristic of a number greater than unity is one less than the number of figures to the left of the decimal point. Consider 225.16. As it lies between 100 and 1000, its logarithm...

...n digits ; then ... log N= (я — 1) + a fraction. Hence the characteristic is n — 1 ; that is, the characteristic of the logarithm of a number greater than unity is less by one than the number of digits in its integral part, and is positive. 437. The Characteristic...

...generally contain- only mantissas of logarithms. The characteristic can be found by the following rule: The characteristic of the logarithm of a number greater than unity is positive, that of a number less than unity is negative. Assuming the number to be written in the form...

...combination of significant figures in a 'mber, wherever the decimal point in the number may occur. The characteristic of the logarithm of a number greater than unity is one less than the number of significant figures preceding the decimal point in the number, while the characteristic of the loga.-ithm...

...1o3 _ 5.026 X 1o6 5.026 X 1o~* 5.026 X 1o~4 3.70122 6.70122 7.70122 4.70122 (a) The characteristic of a number greater than unity is one less than the number of places before the decimal point, thus the characteristics of 4634.2 is 3 63.87 is 1 6.478 is o (b)...

...above argument relating to characteristics it may be found that the following working rules are valid: The characteristic of the logarithm of a number greater than unity is one less than the number of digits in the whole part of the number. The characteristic of the logarithm of a number less than unity...
