is the notation used in physics and
engineering to denote the logarithm to base e, also called the natural
logarithm, i.e.,
 |
The United States Department of Commerce recommends that the notation 
be used in this way to refer to the natural logarithm (Taylor
1995, p. 33).
Unfortunately, mathematicians in the United States commonly use the symbol 
to refer to the natural
logarithm, as does TraditionalForm typesetting in the Wolfram
Language. The use of 
for different purposes by different mathematical communities causes considerable
confusion, so extreme care is needed in determining if the symbol 
found in the wild refers to 
or 
.
The natural logarithm is implemented in the Wolfram Language as Log[x], which is equivalent to Log[E, x].
