|
|
The function <code class="computeroutput"><span class="identifier">prime</span></code> provides
|
|
fast table lookup to the first 10000 prime numbers (starting from 2 as the
|
|
zeroth prime: as 1 isn't terribly useful in practice). There are two function
|
|
signatures one of which takes an optional <a class="link" href="../../policy.html" title="Chapter 20. Policies: Controlling Precision, Error Handling etc">Policy</a>
|
|
as the second parameter to control error handling.
|
|
</p>
|
|
<p>
|
|
The constant <code class="computeroutput"><span class="identifier">max_prime</span></code> is
|
|
the largest value you can pass to <code class="computeroutput"><span class="identifier">prime</span></code>
|
|
without incurring an error.
|
|
</p>
|
|
<p>
|
|
Passing a value greater than <code class="computeroutput"><span class="identifier">max_prime</span></code>
|
|
results in a <a class="link" href="../error_handling.html#math_toolkit.error_handling.domain_error">domain_error</a>
|
|
being raised.
|
|
</p>
|
|
<p>
|
|
This function is <code class="computeroutput"><span class="keyword">constexpr</span></code> only
|
|
if the compiler supports C++14 constexpr functions.
