• A base 10 logarithm (common logarithm) is normally written as log
• A base
written as log
Note that certain publications use "log" to refer to base
take care to watch for what type of notation is being used in the publications you are
working with. This calculator and manual use "log" to mean base 10 and "ln" for base
