<b>Function</b>
<dd>
Exponential Functions.
<p>
<dt>
<b>Syntax</b>
<dd>
<tt>real exp(real x);</tt><br>
<tt>real log(real x);</tt><br>
<tt>real log10(real x);</tt><br>
<tt>real pow(real x, real y);</tt><br>
<tt>real sqrt(real x);</tt>
<p>
<dt>
<b>Returns</b>
<dd>
<tt>exp </tt> returns the exponential <i>e</i> to the power of <tt>x</tt>.<br>
<tt>log </tt> returns the natural logarithm of <tt>x</tt>.<br>
<tt>log10</tt> returns the base 10 logarithm of <tt>x</tt>.<br>
<tt>pow </tt> returns the value of <tt>x</tt> to the power of <tt>y</tt>.<br>
<tt>sqrt </tt> returns the square root of <tt>x</tt>.
<p>
</dl>
<b>Note</b>
<p>
The "n-th" root can be calculated using the <tt>pow</tt> function with a
negative exponent.
<p>
<b>Example</b>
<pre>
real x = 2.1;
printf("The square root of %f is %f\n", x, sqrt(x));
</pre>
