<h2 class="section">D.11 <code>math</code></h2>

<p>The <code>math</code> library exports functions that operate on IEEE double
precision floating point numbers using the host system&rsquo;s C
library. The numbers are represented natively as contiguous blocks of
8 bytes each, and on the virtual side as lists of eight character
representations. (More explanation is given in <a href="Type-Conversions.html#Type-Conversions">Type Conversions</a>.) These functions take the form
</p>
<table><tr><td>&nbsp;</td><td><pre class="example">library('math',f)
</pre></td></tr></table>

<p>where <code>f</code> is a character string identifying the function in most
cases by its standard name in the C library.
