title: faster Math.exp() via JNI?
body: <p>I need to calculate <code>Math.exp()</code> from java very frequently, is it possible to get a native version to run faster than <strong>java</strong>'s <code>Math.exp()</code>??</p>
  
  <p>I tried just jni + C, but it's slower than just plain <strong>java</strong>.</p>
