(2) Logarithmic and Exponential Function Calculations
• A base 10 logarithm (common logarithm) is normally written as log
10
or log.
• A base
e
(
) logarithm (natural logarithm) is normally
written as log
e
or ln.
Note that certain publications use “log” to refer to base
e
logarithms, so you must
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
e
.
