Logarithmic and natural logarithmic functions of values.
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
