Natural logarithm

The natural logarithm is the logarithm to the base e, where e is an irrational and transcendental constant approximately equal to 2.718<span style="margin-left:0.25em">281</span><span style="margin-left:0.2em">828</span>. The natural logarithm is generally written as ln x, loge x or sometimes, if the base of e is implicit, as simply log x. Parentheses are sometimes added for clarity, giving ln, loge or log. This is done in particular when the argument to the logarithm is not a single symbol, in order to prevent ambiguity.
