title: Need a float to display in standard form Obj C
body: <p>I have an app which is calculating values for a filter. These values are usually within the 10^-9 value. At the moment the value of this calculation is sent to a float. Is there an easy way to force this number to display in standard form? i.e x*10^-9 as opposed to having a long decimal.
  Regards</p>
