system out output for double numbers in a java program
- by Nikunj Chauhan
I have a program where I am generating two double numbers by adding several input prices from a file based on a condition.
String str;
double one = 0.00;
double two = 0.00;
BufferedReader in = new BufferedReader(new FileReader(myFile));
while((str = in.readLine()) != null){
if(str.charAt(21) == '1'){
one += Double.parseDouble(str.substring(38, 49) + "." + str.substring(49, 51));
}
else{
two += Double.parseDouble(str.substring(38, 49) + "." + str.substring(49, 51));
}
}
in.close();
System.out.println("One: " + one);
System.out.println("Two: " + two);
The output is like:
One: 2773554.02
Two: 6.302505836000001E7
Question:
None of the input have more then two decimals in them. The way one and two are getting calculated exactly same.
Then why the output format is like this.
What I am expecting is:
One: 2773554.02
Two: 63025058.36
Why the printing is in two different formats ? I want to write the outputs again to a file and thus there must be only two digits after decimal.
