<p>What is the best way to convert a double to a long without casting?</p>

<p>For example:</p>

<pre><code>double d = 394.000;
long l = (new Double(d)).longValue();
System.out.println("double=" + d + ", long=" + l);
</code></pre>

Assuming you're happy with truncating towards zero, just cast:
```
```
double d = 1234.56;
long x = (long) d; // x = 1234
```
```
This will be faster than going via the wrapper classes - and more importantly, it's more readable. Now, if you need rounding other than "always towards zero" you'll need slightly more complicated code.
