<h2 class="section-header" id="differences-from-the-specification"><a href="#differences-from-the-specification">Differences from the specification</a></h2>
<p>There are two places where hexponent differs from the C11 specificaiton.</p>
<ul>
<li>An exponent is not required. (<code>0x1.2</code> is allowed)</li>
<li><code>floating-suffix</code> is <em>not</em> parsed. (<code>0x1p4l</code> is not allowed)</li>
</ul>
<h2 class="section-header" id="no_std-support"><a href="#no_std-support"><code>no_std</code> support</a></h2>
<p><code>no_std</code> support can be enabled by disabling the default <code>std</code> feature for
hexponent in your <code>Cargo.toml</code>.</p>
<pre><code class="language-toml">hexponent = {version = "0.2", default-features = false}
</code></pre>
<p>Disabling the <code>std</code> feature can currently only disables the
<code>std::error::Error</code> implementation for <code>ParseError</code>.</p>
