title: savetxt How change the type from float64 to int or double
body: <p>I have been trying to use the <code>savetxt</code> function in numpy. The problem I am running into is that even thought I define my variables accordingly, i.e. int() or double(), the text file i am getting out has floats in them. How can I change that?</p>
  
  <p>Input is as follows: <code>pNoise=[int(i), around(pNoise[0], decimals=3), around(pNoise[1], decimals=3), around(pNoise[2], decimals=3)]</code></p>
  
  <p>savetxt line is as follows: <code>savetxt(noutF, pNoisetot)</code></p>
  
  <p>What I expect is: <code>0 1.567 8.865</code> instead I get <code>0.000000000000000000e+00 1.015909999999999940e+02 2.600000000000000089e-01</code></p>
