title: Android NDK: 'modfl' was not declared in this scope
body: <p>I am trying to pull some code from another project into an NDK project, and when I build I'm getting the following error:</p>
  
  <pre><code>error: 'modfl' was not declared in this scope
  </code></pre>
  
  <p>In the source file I have <code>#import &lt;math.h&gt;</code> and the call is as follows:</p>
  
  <pre><code>long double tempValLong;
  double tempValDouble; // This is initialized to a decimal number
  long double n = modfl(tempValDouble , &amp;tempValLong);
  </code></pre>
  
  <p>Application.mk includes <code>APP_STL := gnustl_static</code>.  Am I missing something, or does Android not include the modfl function?</p>
