I faced similar issue in javascript which i resolved by multiplying and divinding by 1000. How can I resolve this in Java?
Code snippet:
double a=Double.parseDouble("1.8")/100;
System.out.println(a);
Output:
0.018000000000000002
I want 0.018 as output. Suggestions?
You can do :
double a=Double.parseDouble("1.8")/100;
DecimalFormat df=new DecimalFormat("0.000");
String f = df.format(a);
try {
double dblValue = (Double)df.parse(f) ;
System.out.println(dblValue);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
or
double dblValue2 = Math.round( a * 1000.0 ) / 1000.0;
System.out.println(dblValue2);
