title: Save numpy array to CSV without scientific notation
body: <p>I was able to calculate the mean, min and max of A:</p>
  
  <pre><code> import numpy as np
  
   A = ['33.33', '33.33', '33.33', '33.37']
  
   NA = np.asarray(A)
   NA = NA.astype(float)
   AVG = np.mean(NA, axis=0)
   MN = np.min(NA, axis=0)
   MX = np.max(NA, axis=0)
  
   print AVG, MN, MX
  </code></pre>
  
  <p>What is the easiest way to save those results to a csv documento using python? I dont have one so it needs to be created.</p>
  
  <p>If I use this:</p>
  
  <pre><code> np.savetxt('datasave.csv', (AVG,MN,MX), delimiter=',')
  </code></pre>
  
  <p>It will show as scientific notation in csv. How do I not get that but float?</p>
