title: Numpy n-tuple array with dtype float
body: <p>I need an expression that will grant me an 8-tuple <code>float</code> array. Currently, I have the 8-tuple array via:</p>
  
  <pre><code>E = np.zeros((n,m), dtype='8i') #8-tuple
  </code></pre>
  
  <p>However, when I append an indices <code>i,j</code> via:</p>
  
  <pre><code>E[i,j][0] = 1000.2 #etc.
  </code></pre>
  
  <p>I get back a tuple array with dtype <code>int</code>: </p>
  
  <pre><code>[1000   0   0   0   0   0   0   0]
  </code></pre>
  
  <p>It appears I need a way of using the <code>dtype</code> within my <code>zeros</code> command to both set the n-tuple and the <code>float</code> value.  Does anyone know how this is done?  </p>
