title: Get rid of scientific notation
body: <p>I need to do some calculations but I'm getting a problem with values which are very low, for example, I need to get the 2.7% of 0.005 and I end up with 1.3500000000000003e-4 which is not what I'm looking for, I just need to know how can I get an accurate percetage of those values, what I'm doing right now is <code>&lt;value&gt; * 2.7 / 100</code> which works great for integers or floats greater than 0.05.</p>
  
  <p>For example, the one that I need which is 2.7% of 0.005 needs to be shown as 0.000135.</p>
