    normalize int data

    Hello everyone,


    I have a couple of integers, and I want to find a simple and effective way to normalize them into range [0, 1]. Any ideas and code refer?


    thanks in advance,
    George

    Not sure what you mean. If you mean map from one interval to another, then something like this:
    Code:
    int Min = //Minimum value in your interval
    int Max = //Maximum value in your interval
    int Value = //Value to normalize, maybe from traversing an array
    
    double NormalizedValue = (double)(Value - Min) / (double)(Max - Min);
    (just be sure that Max > Min)

    Using this, in the interval 1 - 5, 1 would map to 0.0, 5 would map to 1.0 and 3 would map to 0.5.

    Thanks Magos,


    I heard there is also a logarithm based normalization approach, do you know how to implement in this way?
