<h3 class="subsection">D.14.2 <code>mpfr</code> unary operators</h3>

<p>Functions with these names take a single <code>mpfr</code> number as an
argument and return a single <code>mpfr</code> number as a result.

<p>The semantics of these functions are similar to those of their
counterparts in the native API, with these provisions.
</p>
<ul>
<li>
The precision of the result is the precision of the argument.
</li><li>
There is no second argument for assigning the result.
</li><li>
The <code>nextabove</code> and <code>nextbelow</code> functions do not modify
their arguments in place, but return a freshly allocated result
like all other functions.
</li></ul>
