<h1>LOG Function</h1>
<p>The <b>LOG</b> function is one of the math and trigonometry functions. It is used to return the logarithm of a number to a specified base.</p>
<p>The <b>LOG</b> function syntax is:</p>
2017-08-10 10:05:49 +00:00
<p style="text-indent: 150px;"><b><em>LOG(x [,base])</em></b></p>
2016-03-11 00:48:53 +00:00
<p><em>where</em></p>
2017-08-10 10:05:49 +00:00
<p style="text-indent: 50px;"><b><em>x</em></b> is a numeric value greater than 0</p>
2016-03-11 00:48:53 +00:00
<p style="text-indent: 50px;"><b><em>base</em></b> is the base used to calculate the logarithm of a number. It is an optional parameter. If it is omitted, the function will assume <b><em>base</em></b> to be 10.</p>
<p>The numeric value can be entered manually or included into the cells you make reference to.</p>
<p>To apply the <b>LOG</b> function,</p>
<ol>
<li>select the cell where you wish to display the result,</li>

2016-03-11 00:48:53 +00:00
</li>
