<i>Mathematical functions</i> are used to perform mathematical
operations.
<p>
The following mathematical functions are available:
<ul>
<li><a href=242.htm>abs()</a>
<li><a href=244.htm>acos()</a>
<li><a href=244.htm>asin()</a>
<li><a href=244.htm>atan()</a>
<li><a href=243.htm>ceil()</a>
<li><a href=244.htm>cos()</a>
<li><a href=245.htm>exp()</a>
<li><a href=243.htm>floor()</a>
<li><a href=243.htm>frac()</a>
<li><a href=245.htm>log()</a>
<li><a href=245.htm>log10()</a>
<li><a href=242.htm>max()</a>
<li><a href=242.htm>min()</a>
<li><a href=245.htm>pow()</a>
<li><a href=243.htm>round()</a>
<li><a href=244.htm>sin()</a>
<li><a href=245.htm>sqrt()</a>
<li><a href=243.htm>trunc()</a>
<li><a href=244.htm>tan()</a>
</ul>
<b>Error Messages</b>
<p>
If the arguments of a mathematical function call lead to an error, the
error message will show the actual values of the arguments. Thus the
statements
<pre>
real x = -1.0;
real r = sqrt(2 * x);
</pre>
will lead to the error message
<pre>
Invalid argument in call to 'sqrt(-2)'
</pre>
