Question

I am trying to convert string to double. But i am getting the number format exception. The code that gives the exception is like this:

double B = Double.parseDouble(s);

I take the s value from server to my application. And it is like this:

fd485b154a0427fa75c0428cdafac71f

Any solution?

Answer 1

Try this: (i am assuming the string is HEX coz of the 0-9 & a-f in it)

double doubleVal = new BigInteger("fd485b154a0427fa75c0428cdafac71f", 16).longValue();
long longVal = new BigInteger("fd485b154a0427fa75c0428cdafac71f", 16).longValue();
System.out.println(doubleVal);
System.out.println(longVal);

This gives:

8.4848548707027374E18
8484854870702737183
