Avoiding exponential notation while outputting doubles to file

Hi all,

I am writing doubles to a file. For very small or large numbers the output is in "E notation format"

For example

double d = 0.0009

filePrintStream.println(d);

This puts 9.0E-4 in the output file. How can I just make it enter 0.0009 and not 9.0E-4 ?

Many thanks,

Greg.
