Common Logarithms Mantissa and Characteristic - Tutor-USA. A logarithm is composed of a characteristic and a mantissa Characteristic it is from CHM 2045 at University of Central Florida, Characteristic and Mantissa вЂў The characteristic of the logarithm of any number greater than 1 is positive and is one less than the number of digits to the left of the decimal point in the given number. Example: Consider the following table . 27 Number . Characteristic ; 48 . 1 : 3578 . 3 : 8.31 . 0 : Rule 2 вЂў The characteristic of the logarithm of any number less than 1 is negative.

The part of a logarithm to the base ten that is to the right of the decimal point. For example, if 2.749 is a logarithm, .749 is the mantissa. For example, if 2.749 is a logarithm, .749 is the mantissa.

The decimal part of the logarithm, which we obtain from logarithm tables, is called the mantissa. So, logarithm of a number consists of two parts: the integral part called the characteristic, the decimal part, the mantissa. Table 8-8 shows the characteristic, mantissa, and logarithm for several positions of the decimal point using the sequence of digits 4, 5, 6. It will be noted that the mantissa remains the same for that particular sequence of digits, regardless of the position of the decimal point.
