How to obtain DBL_MIN without #include <limits> in C++
<p>I'm writing a header/cpp file pair and want to minimize the things I need to include in the cpp file. I use <code>#include &lt;limits&gt;</code> to access <code>DBL_MAX</code>, and wanted to know if there's another way to get that value and stick it in a variable. By the way, it looks like bit manipulation is not allowed/supported in C++.</p>
<p>It is also crucial that the value is exactly the maximum value down to the last bit, not &quot;close&quot; to it.</p>
