have a look at parseDouble()

There are many ways to kill a cat. It depends on which method suites u and what you want to achieve.

I will do it by an anonymous instantiation of a Double wrapper class, - because all wrapper classes have a constructor that takes in a String argument to create the wrapper instance - with your input string. Then use the no-arg unboxing method of that Double wrapper class -(doubleValue()) -to get the primitive value of type double. all this is done in one line. Here it is -:

dTot = new Double("11316500.00").doubleValue();

Do you mean that you tried the parseDouble method and it didn't work?
The link is pretty clear to me.

Hi
this might help you.

when i do parseDouble i get 1.138606E7 not as 113860650

when i do parseDouble i get 1.138606E7 not as 113860650

suppose if i get a double value as 1.138606E7 , then how do i convert it to double value 11386065.00

look at the DecimalFormat references of the java.text package on the net. THat can be used to format the output. Something like-:

//where doIt is a double
new java.text.DecimalFormat("#,##0.00")).format(doIt)

by default System.out.println() prints large double values in exponential format - you can now format the output using System.out.printf() which is similar to the C printf() function
try

 String s="113860650";
 double x=Double.parseDouble(s);
 System.out.println(x);
 System.out.printf("%f", x);

which prints
1.1386065E8
113860650.000000

that is handy horace1. Cool!!!!!!!

Technically that is not converting it to a double value.
1.138606E7 is the double value. What you probably want is convert it to a string in which case the suggestions you've got will work.
