		<summary type="html">&lt;p&gt;Created page with &amp;quot;In &lt;a href=&quot;/index.php/Mathematics&quot; title=&quot;Mathematics&quot;&gt;mathematics&lt;/a&gt;, the &amp;#039;&amp;#039;&amp;#039;natural logarithm&amp;#039;&amp;#039;&amp;#039; of a &lt;a href=&quot;/index.php/Number&quot; title=&quot;Number&quot;&gt;number&lt;/a&gt; is its &lt;a href=&quot;/index.php/Logarithm&quot; title=&quot;Logarithm&quot;&gt;logarithm&lt;/a&gt; to the base of the mathematical constant e, where e is an irrational and transcendental ap...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;In [[mathematics]], the '''natural logarithm''' of a [[number]] is its [[logarithm]] to the base of the mathematical constant e, where e is an irrational and transcendental approximately equal to 2.718281828459. &lt;br /&gt;
&lt;br /&gt;
== Description ==&lt;br /&gt;
&lt;br /&gt;
The natural logarithm of x is generally written as ln x, loge x, or sometimes, if the base e is implicit, simply log x.&lt;br /&gt;
&lt;br /&gt;
Parentheses are sometimes added for clarity, giving ln(x), loge(x) or log(x). This is done in particular when the argument to the logarithm is not a single symbol, to prevent ambiguity.&lt;br /&gt;
&lt;br /&gt;
The natural logarithm of x is the power to which e would have to be raised to equal x. For example, ln(7.5) is 2.0149..., because e2.0149... = 7.5. The natural log of e itself, ln(e), is 1, because e1 = e, while the natural logarithm of 1, ln(1), is 0, since e0 = 1.&lt;br /&gt;
