Siobhan,
Yes, before reading your posting, a possible solution hit me at about 3:30am. Luckily, today is my day off, so staying up insanely late like that wasn't a problem.
I used a for loop to iterated an index array, and then used the += to add it to the last array.
for ( i = 0 ; i < 64 ; i++ )
{
total += Double.parseDouble ( value[i] );
}
Help me out here, if you can. An integer won't hold the value of 2^63, will it? You have to do some casting in this problem, don't you. My solution works, but I'm not sure it's correct.
