Converting Double to String

[ananth]

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

Double do=123456789012 3456.12;
String str=Double.toSt ring(do);

when i execute it i am getting the values in exponential format.
which is like: 1.2345678901234 56E15

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 = 123456789012345 6.12;
String aString=Double. toString(aDoubl e);
System.out.prin tln(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 == 9.0071992547409 92E15 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("123 4567890123456.1 2");
System.out.prin tln(myBigDecima l.toPlainString ());
