    How to Calm Unruly [ARRAYS]

    I am using a looped array in which a mathematical equation is derived. I have set the following:

    int answer;
    answer = AnotherEquation * TheSecondEquation + AbunchOfOtherCrud
                    / ThisGetsPrettyComplicated;
     loop goes here:::::::::::
      if answer = array1[i]/array2[z]  
        {then do this}
    The problem is it is too sensitive. I would like to set ranges (+/- 5%) in order to find a ballpark or I would never get an answer.

    I would prefer to have the range set in the output from the array (for instance the higher the number the more range I would like -whereas the lower numbers would receive less range).

    Thanks to all! I appreciate you not letting me feel like a total C++ moron.

    It is quite hard to tell anything. What exactly are you doing? What are array1 and array2? Where do you get i and z from etc.
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    So, if the values are within 5 percent, array1[i]/array2[z] should be between 0.95 and 1.05.

    Take the absolute of the difference, convert it to floating point, divide by the original value and see if the result is <= 0.05.
    All the buzzt!
