37        The TR adds 23 special functions (plus float and long double overloads) to
38        header &lt;cmath&gt;. However, at present there is no Boost License compatible
39        implementation of these functions, so these are <span class="bold"><strong>unsupported
40        by this implementation</strong></span> unless your standard library supports them
41        itself.
