    Default Calculationg the percentage.

    I am trying to calculate a percentage.

    double percentage = (numberMatchedEntries / numberEntriesFile1) * 100;
    numberMatchedEntries = 20
    numberEntriesFile1 = 52

    So the output would be about: 38.1%

    But from this code:
    (numberMatchedEntries / numberEntriesFile1)
    I only get 0 back, and not 0,381

    I tried using a float too, but it still keeps 0.
    And I realy don't know why?

    What data types are used in the formula? With integer arithmetic: 6/10= 0
    using doubles: 6.0/10 = 0.6
    If you don't understand my answer, don't ignore it, ask a question.

    That would be it.
    Those two are int's.
    I will change that.

    Thanks.
