Logarithmic and natural logarithmic functions of values. 

Logarithm and Anti-Logarithms

Example #1: When taking the log of a number the number of digits in the mantissa of your answer is equal to the number of significant figures in the problem. 

Example #2: Provide the answer with the correct number of significant figures for each of the following:

a) log(1.15 x 10-5)                                    b) log(100.)

When taking the antilog of a number the number of significant figures in the answer is equal to the number of digits in the mantissa of the problem. 

Example #3: Provide the answer with the correct number of significant figures for each of the following:

a) antilog(-4.18)                     b) 100.0033
