double to string

[zamba]

hi, i want to know how to convert a doble value like this 98.34 to
string 00009834 or 9.34 to 00000934 thanks a lot !!!!!

thank you , but i read link and i tried to use NumberFormat , but i
can't get an example how to use exactly the way i need...

In that case I would just replace the "." with and empty string, count
the remaining letters and add as many zeros as you need.

Check out the DecimalFormat class.

Check out the DecimalFormat class.

I guess, it would be easier, if he(zamba) first multiplied with
100, and then used some integral format.

I think it goes something like this:

assume you have a double n with a value of 9.34 which you want to display as
009.34 string.
NumberFormat nf = NumberFormat.getNumberInstance();
//set the min digits before the decimal
nf.setMinimumIntegerDigits(3);
//set min digits after decimal
nf.setMinimumFractionalDigits(2);
String numberToShow = nf.format(n);
//numberToShow will be your string

String numberToShow = nf.format(n);
//numberToShow will be your string

But to follow up: You would not format 98.34 to display as "00009834"
because then it would not be the same number.

final DecimalFormat df = new DecimalFormat("00000000");
df.setMultiplier(100);

DecimalFormat.setMultiplier()

How you format the number for display or storage has no effect on what the
number is.

Plenty of formats use implicit decimal points, so the OP would indeed have
"the same number" given the implicit location of the decimal point.

It is no more sensible to say the number is "not the same" than to say that
the European-format "9,834" does not represent the same number as the
American-format "9.834", or to claim that the European "9.834" does.
