Logarithms and Antilogarithms
Be especially careful in rounding the results of calculations involving logarithms. The following rules apply to most situations and are illustrated in Example 1.1:
1. In a logarithm of a number, keep as many digits to the right of the decimal point as there are significant figures in the original number.
2. In an antilogarithm of a number, keep as many digits as there are digits to the right of the decimal point in the original number.
