I'm pretty new to Java and I am currently working on a project where I need to work with Floating points.

I am trying to convert the value from 3.5E8 (Double value) to a string value of 350000000. I have looked on the internet but currently I can't find a solution.

Look at DecimalFormat. –  Andrew Thompson Jun 13 '13 at 12:29
    
System.out.println(new BigDecimal(f).toPlainString()); ? –  Alexis C. Jun 13 '13 at 12:30
    
way2java.com/string-and-stringbuffer/… + many other conversion/casting examples. Recomend to book –  Viliam Jun 13 '13 at 12:34
    
Although the answers so far will work for 3.5E8, they may not do what you want for some other inputs. You need to consider the range of inputs before selecting a solution. –  Patricia Shanahan Jun 13 '13 at 12:39

Use:

new BigDecimal(yourValue).toPlainString();

Perfect, just what I wanted. Thank you. –  Michael Jun 13 '13 at 12:46

try String.format

String str = String.format("%.0f",3.5E8);

or

String str = new DecimalFormat("#.#").format(3.5E8);

You can use the BigDecimal class , toPlainString() method :

Returns a string representation of this BigDecimal without an exponent field. 

 System.out.println(new BigDecimal(doubleValue).toPlainString());
