Java floating point math - (conversion for feet/meters)

Question

Pretty basic question I think - I\'m performing this function:

private double convertMetersToFeet(double meters)
{
  //function converts Feet to Meters.
             


        

Answer 1

I'm answering my own question for posterity's sake. I used the DecimalFormat answer above, but the answers failed to take into account the return type of the method.

Here's the finished code:

  private double convertMetersToFeet(double meters)
{
  //function converts Feet to Meters.
      double toFeet = meters;
      toFeet = meters*3.2808;  // official conversion rate of Meters to Feet
      String formattedNumber = new DecimalFormat("0.0000").format(toFeet); //return with 4 decimal places
      double d = Double.valueOf(formattedNumber.trim()).doubleValue();
      return d;
}
