BigInteger

[7cardcha]

I have some code to add *very* large numbers.

import java.math.*;

public class charles {
	public static void main(String[] args) {
		BigInteger a1 = new BigInteger("46376937677490009712648124896970078050417018260538");

Problem is sum is always = to 0. Are my numbers to big or am I doing something else wrong? Please help.

[Junky]

Did you read the API to see what the add method does?

[7cardcha]

Nope I just jumped into it. Let me check that out.
EDIT
Since a mod needs to approve my next post Ill just edit this one. I figured out the problem. It needs to be sum = sum.add(a99)
I fixed it. However the answer it is giving seems to low(Or just plain wrong) I am trying to do http://projecteuler.net/problem=13 And the answer I give it is not right.

[7cardcha]

Ok I fixed the problem it should be sum = sum.add(a99)
But the answer it is returning seems much to low(5500268942856974534503250748612148381527149696 152422)
Are the numbers to big?
This is what I am trying to do Problem 13 - Project Euler The answer I give it is not right. What is wrong?

[7cardcha]

WHY ARE MY POSTS NOT APPEARING. I fixed the problem but the number it gets seems to low. Is there some kind of limit?

[Fubarable]

You are a new poster, and the software requires that your posts be approved by a moderator to be visible. I've just done this. Sorry for the inconvenience, but it does help to keep out spam.

[7cardcha]

Ok thanks:D It appears my posts are spam because I posted like 3 times because I thought for some reason I was not posting right 0.o

[Junky]

1. The problem states to sum 100 numbers. Your code only has 99 numbers.
2. Disply first 10 digits of result. Your code displays the full result.

[7cardcha]

Thanks it worked. I am such a retard.(PS I didn't have problem 2 I only copy/pasted the first 10 digits)

[JosAH]

But the answer it is returning seems much to low(5500268942856974534503250748612148381527149696 152422)
Are the numbers to big?

The third digit from the left in your answer is incorrect. I just checked it (my answer seems to be correct) but you must have a typo somewhere in that big ugly list.

kind regards,

Jos
