Parsing Double numbers
I am trying to write a program for some maths coursework,and I am having problems compiling it on my laptop,but I can compile it on the university unix machines!
Specifically,the line of code that appears to be causing the trouble is the following line of code :-
double number = Double.parseDouble(stdin.readLine());
When ever I try and compile the program on my laptop (it's running Windows by the way),i get an error message,saying that it cannot resolve symbol,with the ^ pointing to the full stop,ie between "Double" and "parse".
Any help in rectifying this problem would be greatly appreciated.
Thanks very much.
to compile my code I am just using the command javac
through the comman line?
I really cant undestand the problem!Well, unfortunately javac doesn't have a -version option (at least prior to the 1.5 / 5.0 version). But I heard that the newest version does. What does javac -version display? If it doesn't show a version number but instead says something like "invalid flag: -version", then I'd guess that the version of that tool is old. Did you really install the JDK and not just JRE? Or maybe you goofed up an installation and ended up with an old javac tool in your PATH ahead of the version that you want.

Problem with the addition of double numbers
when we try to add the two double numbers say,
119.52, 10.00
here we should get 129.52
but it is giving as 129.51999999999998
This is happening only for sum numbers.
Here i want to round this to two digits after decimal point
if i round the above value i will get 129.52 and the problem will be solved.
But we don't know exactly on what basis we are getting the sum as 129.51999999999998.
Assume that, tomorrow when we are adding some other numbers we may got like
129.51444444444448
when we round this we get 129.51
but actually we have to get 129.52.
If anyone know why the system is giving that wrong sum , please give solution to avoid this.
In My application , i want the exact sum amount so if i add some numbers i should get exact sum.
like 119.52+10=129.52
i want exactly this. How to get this.As another poster said, this is a topic worth reading up on, as there are subtleties involved in this kind of imprecise math. A couple of points to get you started though...
* Java's double type has a precision of something like 16 (20? 24?) decimal places. (You should be able to find the correct number in the lang. spec., or someone may be kind enough to post it here.) I don't remember the formal definition, but what this means, approximately, is that any number that can be represented will be accurate to within +/-0.5*10^-16 of its value. That is, if the actual value is 2e5, then the absolute value of the error in the representation will be less than 0.5e-11. (I might be off be a factor of 2 and/or an order of magnitude here, but you get the general idea.) The good news is, no value will be in error by more than that amount. The bad news is, any value could be in error by up to that amount. These are the two key points.
* Compare the precision implicit in your data and needed in your results to that of Java, along with the number of intermediate calculations you'll do to get a final result. For instance, if you're doing financial calcs in the tens of billions of dollars, and you need accuracy to the penny, that's one part in 10^-12. Assuming any given value is off by no more than one part in 10^-16, and assuming all errors are in the same direction, if you do 10^4 cumulative additions, you'll be off by a penny. Again, these are rough, and I may have missed something, but this is the kind of thing to look at to determine how the inherent imprecision will affect you.
* Don't round any intermediate results. Keep the precision you have. However, when you're comparing (as jschell demonstrated) make a copy of the value and round that copy before doing the comparison. Use the first two points above to determine whether that rounding will meet your needs for precision. Same goes for displaying.
* Finally, if the 10^-16 (or whatever it was) precision of a double is not sufficient, you can get arbitrary precision with BigDecimal. There are a couple of caveats, however. 1) It's a lot slower than using primitives ans 2) Arbitrary precision does not mean infinite precision. You can specify as many decimal places as you want (subject to time and memory constraints), but you even if you specify 1,000 decimal places, you can still be off by 5 in the 1001st place. -
Adding two special double numbers
Adding two double numbers.
say, 12543.34 and 42895.00 am getting in the decimal part .3999999.

Adding two double numbers is a problem
Hi friends..
when we try to add the two double numbers say,
119.52, 10.00
here we should get 129.52
but it is giving as 129.51999999999998

But we don't know exactly on what basis we are getting the sum as 129.51999999999998.
Assume that, tomorrow when we are adding some other numbers we may got like
129.51444444444448
when we round this we get 129.51
but actually we have to get 129.52.
If anyone know why the system is giving that wrong sum amount, please give solution to avoid this.
To solve this problem, i tried by converting the double numbers to integers and adding these integers and finally converting the sum into double...like
if
d1= 119.52
d2=10
int x = (int)(119.52*100.00);
int y = (int)(10.00*100.00);
int z = x + y;
double d = (double)(z)/100;
This is working for this case...
But when we are applying this approch to other numbers it is giving problem....
i.e, if i convert like below
int x = (int)(72.46*100.00);
this should give x=7246
but it is giving x=7245
What is the solution for this problem...please give immediate reply.....Assume that, tomorrow when we are adding some other
numbers we may got like129.51444444444448
That isn't going to happen. The numerical computations are deterministic. The problem lies in your understanding of how numbers work.
This has been repeated before so if you want more detail I suggest you search the forums for discussion on precision and double.
Computers store numbers in binary. The number you are trying to represent is a decimal number. This produces an error in precision.
The same problem exists in decimal notation. Decimal notation can not accurately represent one divided by three (in decimal 0.33333333.....). -
Parsing doubles with NumberFormat
I have a little class called TextFieldDouble wich can display and parse double values. Depending on the default locale '.' or ',' is used for decimal separator and the opposite for grouping. I want to disable grouping because the user should get a parsing error when entering the wrong decimal separator. But java does not throw a ParseException in case of grouping disabled but truncates the string and returns a long. In case of trash after a number no exception is thrown, too.
Here a little code that demonstrates my problem:
public static void main(String[] args) {
try {
java.text.NumberFormat f = java.text.NumberFormat.getNumberInstance(java.util.Locale.US);
System.out.println("With grouping:");
System.out.println(f.parseObject("1.003").toString());
System.out.println(f.parseObject("1,003").toString());
System.out.println(f.parseObject("1ccc0").toString());
System.out.println("Without grouping:");
f.setGroupingUsed(false);
System.out.println(f.parseObject("1.003").toString());
System.out.println(f.parseObject("1,003").toString());
System.out.println(f.parseObject("1ccc0").toString());
catch (Exception e) {
e.printStackTrace();
The output is:
With grouping
1.003
1003
1
Without grouping
1.003
1
1
But I want an exception in case of 1,003 when grouping disabled or in case of 1ccc3 anyway. Has anybody an idea?I'm having the same problem. Have you been able to fix it?
Thanks. -
Problme while adding double numbers.
Hi,
I am trying to get a series of double numbers by adding some constant value to a double number.
so when i try to add .01 to 10.04 i am getting the result as 10.0499999.. instead of 10.05
is there any work around for this problem.
ThanksCan Someone tell me please what is going on?
Trying to add simple double numbers but the result is really surprising.
double postage = 0.72 ;
double total = 0.18;
double totalamt = postage + total;
System.out.println(totalamt);
Result: 0.8999999999999999 INSTEAD OF 0.9 -
hi, I am trying this:
double a = 10;
double k;
BigDecimal bd = new BigDecimal(a);
bd = bd.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println(bd);
k = bd.doubleValue();
System.out.println(k);and I get this:
10.00
10.0
which is confusing, because I need to display double numbers with 2 precision digits (DecimalFormat is not usable because it returns Strings)
I could do that with C, is this possible in Java?xpanta wrote:

Formatting is something you do when you print.

Hello,
We are working on an integration that needs the phone numbers in CRMOD parsed out into the individual components. Currently the Web Services provide a phone number in it's full form. We would like to get the country code, area code, phone number, and extension as separate values. In CRMOD this is automatically done when you click on the "phone" icon. I'm not sure if CRMOD stores these values separately, or if this is just an algorithm. If it is an algorithm, has anyone re-created it?
Thanks.

Array functions on non-double numbers
Hey everyone,
Sorry for another newbie question, coming from Labview has spoiled me Is there a way to use the Array Operations functions on float numbers? If not, can anyone recommend a Boost like library that is C based that will handle floats?
Thanks,
AustinI suppose you are referring to array functions from the Analysis library: unfrtunately those functions are limited to treat doubles only. I don't know of any alternative for floats or doubles: for the simpler of them you may want to create your own equivalent in a for loop; for more complex functions you can create a temporary array of doubles and use ConvertArrayType function to exchange data to and from it before and after calling the array function.
Depending on other functions you are using into your application, you can consider promotinig all of your arrays to double and use them: PC are now plenty of memory to use and very fast CPU frequency so it could be a feasible solution.
Proud to use LW/CVI from 3.1 on.

Noise while formatting double numbers
Hi all,
When I try to format a number with 10 to 12 decimal point, I get noise as the number gets bigger. I know this is because computer can not handle all the floating point numbers when converted to binary. I wanted to see if any one know how to find out how many decimal points I can saw for perticular number with out getting noise at the end. For example, if you try to format double number like 99999.99 using snprintf and try to have 12 decimal points them you get 99999.990000000005. Is there any way to avoid this and work around.
Thanks...Look up the DecimalFormatter/NumberFormatter APIs.

I have been trying to figure out my problem for several hours, but still didn't get it. Hope to get an idea from you guys. My code is as follows:
var astr;
var outCr ="|";
var outLf = "\u0000";
var cr = "\n";
var lf ="\r";
var ddQuote=""";
var dtQuote='\"';
astr = "<%=firstDesc%>";
astr.replace(outCr,cr);
astr.replace(outLf,lf);
astr.replace(ddQuote, dtQuote);
while (astr.indexOf(outCr) > 0) {
z = astr.indexOf(outCr);
astr = astr.substring(0, z) + cr + astr.substring(z+1,astr.length );
while (astr.indexOf(outLf) > 0) {
z = astr.indexOf(outLf);
astr = astr.substring(0, z) + lf + astr.substring(z+1,astr.length );
while (astr.indexOf(ddQuote) > 0) {
z = astr.indexOf(ddQuote);
astr = astr.substring(0, z) dtQuote astr.substring(z+1,astr.length );
document.form1.description.value=astr;
The value of firstDesc is a very big string from the database that contains carriage return, linefeed, single quote and double quote. It needs to be displayed in a HTML text area. Now everything works fine except the double quote. A firstDesc value containing double quote will not appear in the text area, and it even stop my jsp page and disable other buttons. But if I get rid of the code handling the double quote, everything works fine. What's the problem?maybe you should ask this question in a JavaScript forum.

Parsing long numbers as strings
Hi
Is there any way you can prevent a long number being converted to scientific notation? I have to write a method that substrs out each numeric character from a long positive whole number but when the number gets lon it falls over as the number is converted to scientific notation containing '.' and 'E' etc
Any help would be appreciated
CheersHi guys
Thanks for the replies. I think the FM with 63 9s will probably be the simplest.
I'm sorry I wasn't able to post an example as I was just heading out of the office for the day, but have got home so, for completeness will try to pen an example...although I don't have a server here so will be guessing syntax etc :-)
Please forgive me if it doesn't run first time, but it should convey the intention...if necessary I'll debug it in the morning.
Cheers

while k >0 loop
for i in 1...length(mystring) loop
thisnum != to_number(substr(mystring,i,1));
retnum := retnum +thisnum;
end loop;
if length(retnum) > 60 then
mystring := 'retnum';
else
k :=0;
end if;
end loop;
--in the real case the retnum value would be stored at this point
end;
the 'while' loop if needed for very long strings where the 'addition' step hasn't decreased the length enough to be parsed as a number, the problem I have encountered only happens when the resulting number from the first run is long enough for an implicit conversion to scientific notation, this example may not be long enough to trigger it. -

Output is Ray#Cavender#111#M#40#[D@503429#1 between last and second to last is the Membership_id and is coming out as garbage.System.out.println(fname[i] + "#" + lname[i] + "#"+ memId[i] + "#" + gender[i] + "#" +
age[i] + "#" + Membership_fee + "#" + Silver_sneaker_member);
You probably want this to be:
System.out.println(fname[i] + "#" + lname[i] + "#"+ memId[i] + "#" + gender[i] + "#" +
age[i] + "#" + Membership_fee[i] + "#" + Silver_sneaker_member); -

I'm trying to use NumberFormat to validate a string containing a formatted number but having a lot of problems. First, invalid strings are just ignored (same thing as http://forum.java.sun.com/thread.jsp?forum=31&thread=157703)
Also in French, space is used as thousands separators, however if I use a string with space only only the thousands are parsed, i.e.:
String value = "1 234,45";
try {
Number number = NumberFormat.getNumberInstance(Locale.FRENCH).parse(value);
System.out.println(number.floatValue());
} catch (ParseException e) {
e.printStackTrace();
}The output:
1.0
Any help? Thanks!With the NumberFormat, you will get an exception only if the very first character is not parseable. But you don't have to write your own parse routine, just do this:
import java.text.*;
import java.util.*;
public class number {
public static void main(String[] args) {
try {
DecimalFormatSymbols df = new DecimalFormatSymbols(Locale.FRENCH);
df.setDecimalSeparator(',');
df.setGroupingSeparator(' ');
DecimalFormat NF=new DecimalFormat("#,###.##",df);
String out=NF.format(-1234.56);
System.out.println(out);
ParsePosition PP=new ParsePosition(0);
Number number = NF.parse(args[0],PP);
if (PP.getIndex()!=args[0].length()) System.out.println("Parse Exception");
System.out.println(number);
} catch (Throwable exception) {
exception.printStackTrace();
}V.V.
