    Default Array loop problem which returns the difference between the value with fixed value

    Good Morning

    I hope I can explain a problem that I've tried to code but having problems with.

    I have an array of 20 numeric values and the each value is passed (in a loop) along with a fixed value (1.50) to a function that returns the difference between the two.

    I have the function coded and working correctly.

    for instance

    array[0] - 1.50 = 3
    array[1] - 1.50 = 2
    array[2] - 1.50 = 0.5

    etc etc

    This has to be done in the loop until the the program finds the first element in the array with a difference of less than 1.

    So for instance in the example above if the value of array[2] = 2. then the loop would stop there as it's the first element in the array with a difference < 1.

    I can't get the loop structure coded correcty, I trust I need a while loop and a for loop.

    Hope you can see the problem and help if possible. Please let me know if you need clarificatiion.

    Regards

    JS

    It would help if I saw your function but ill give it a go:

    for(i=0;i<array.length;i++)
    {
    if(array[i]-1.50< 1)
        {
           break;
    }
     
    }

    Thanks Fendaril

    I think I'll be OK with that. At the break point I would like to assign a value to a variable that equals the element in the array where it breaks.

    Such as var breakPoint = point in array where break occured.

    Incidentally the user has now requested I code this in Javascript but I can adapt any code you advise.

    Thanks Again

    for(i=0;i<array.length;i++){
       if(array[i]-1.50< 1){
            x = array[i];
            break;
       }
    }
    Please don't ever get confused between Java and JavaScript.

    Thanks Chris

    I won't confuse them and I know they arent the same. It's just the user decided he wants to distribute the code as an HTML file for users to run in Firefox.

    Cheers for your help.
