title: read float from SQLite
body: <p>I used the codes below to load data(float) and store in an array.
  My oject has one float field 'value' (setValue,getValue to read or write value)</p>
  
  <pre><code>rowData=(char*)sqlite3_colum_text(statement,0);
  float v=[[NSString  initWithUTF8String:rowData] floatValue];
  [myObject setValue:v];
  [myArray addObject:myObject]; 
  </code></pre>
  
  <p>If I read the value from the array using
      float tem=[[myArray objectAtIndex:i] getValue];</p>
  
  <p>I found all values are not correct, everyone is 0.00000000000000</p>
  
  <p>Welcome any comment</p>
  
  <p>Thanks</p>
