storing java float/double as a string

14 New Member
I want to store a float/double as String. I have an input file with a column with float values i.e. have the form 1.4E15. I want to store these values as Strings. Here is my code which is resulting in storing 1.4E15 not the value as a String.

Expand|Select|Wrap|Line Numbers
  1.  
  2. String accNumber="";//declaring and initialisation
  3.  
  4. //open file and read line then store the column in accNumber
  5. //the line read has been stored into an array String split[]
  6.  
  7. accNumber=split[2].trim();
  8.  
  9. //how do I make sure it does not store 1.4E15

Look at this Code.

Expand|Select|Wrap|Line Numbers
  1. double d = 1.4E15;
  2. BigDecimal bd = new BigDecimal(d);
  3. System.out.println(bd.toPlainString());
