Double to string giving extra values

[sinsand]

hi all,

i have encountered a issue in java and the issue is --

if my decimal no is 0.001 to 0.009 and when i am converting double to string

it is giving string as 0.0010 to 0.0090

the following code is what i am trying to do

double d1 = 0.006;
System.out.println("d===>"+ d1);
String temp1= String.valueOf(d1);
System.out.println("temp1===>"+ temp1);

if(temp1.indexOf(".")!=-1 && (temp1.substring(temp1.indexOf(".")+1).length()>3) ){
System.out.println("yes in the if condition");
}
else
{
System.out.println("no in the else part");
}


due to the requirement i cannot use Bigdecimal or decimal formater as we are doing validation operation on the resulting string.

can any one suggest any solution for that or any work around this problem ???

and is this a java issue ???

Bug ID: 4428022 System.out.println(0.001) outputs 0.0010

I'm not overly familiar with Java bug reports, but I see a reference to '7' in the 'Release Fixed' field which makes me suspect this is still current.

A kludge would be:

System.out.println(Double.toString(0.006d).replaceFirst("0*$", ""));
