Converting Double to String

[ananth]

Hi All,
I need to convert a Double value to String.The requirement is as follows

Double do=1234567890123456.12;
String str=Double.toString(do);

when i execute it i am getting the values in exponential format.
which is like: 1.234567890123456E15

But i need the values to be converted exactly into String.I cannot use BigDecimals due to the requirements.

The code is as follows.

public class test1 {
public static void main(String[] args) {
double aDouble = 1234567890123456.12;
String aString=Double.toString(aDouble);
System.out.println(aString1);}
}

Please help me in this regard as it would be help ful for my project completion.

Thanks in Advance!!!

Have a look at what the DecimalFormat can do for you.

A double uses 53 bits for its mantissa (or 'significand'). That implies that the
order of magnitude between the leftmost (most significant) and rightmost bit
(least significant) is 2^53 == 9.007199254740992E15 so at most 16 (a bit less)
significant decimal digits can be stored in a double. Your value (which also is
a denormalized value) tries to use more digits than that and you can never store
it without a bit of loss of precision (those rightmost digits).

kind regards,

It is not possible to receive such a BigDecimal in a Double.
The easiest thing you can do is:

BigDecimal myBigDecimal = new BigDecimal("1234567890123456.12");
System.out.println(myBigDecimal.toPlainString());
