<p>
|

The <code class="computeroutput"><span class="keyword">typedef</span> <span class="identifier">float_fast</span><span class="special">#</span><span class="identifier">_t</span></code>, with
|
|
# replaced by the width, designates the <span class="bold"><strong>fastest</strong></span>
|
|
floating-point type with a <span class="bold"><strong>width of at least # bits</strong></span>.
|
|
</p>
|
|
<p>
|
|
There is no absolute guarantee that these types are the fastest for all purposes.
|
|
In any case, however, they satisfy the precision and width requirements.
|
|
</p>
|
|
<p>
|
|
Fastest minimum-width floating-point types are provided for all existing exact-width
|
|
floating-point types on a given platform.
|
|
</p>
|
|
<p>
|
|
For example, if a platform supports <code class="computeroutput"><span class="identifier">float32_t</span></code>
|
|
and <code class="computeroutput"><span class="identifier">float64_t</span></code>, then <code class="computeroutput"><span class="identifier">float_fast32_t</span></code> and <code class="computeroutput"><span class="identifier">float_fast64_t</span></code>
|
|
will also be supported, etc.
