Evenly divide in c#

Question

In c# how do I evenly divide 100 into 7?

So the result would be

1. 16
2. 14
3. 14
4. 14
5. 14
6. 14
7. 14

Answer 1

Not sure why you are working with doubles but wanting integer division semantics.

    double input = 100;
    const int Buckets = 7;
    double[] vals = new double[Buckets];
    for (int i = 0; i < vals.Length; i++)
    {
        vals[i] = Math.Floor(input / Buckets);
    }
    double remainder = input % Buckets;
    // give all of the remainder to the first value
    vals[0] += remainder;

example for ints with more flexibility,

    int input = 100;
    const int Buckets = 7;
    int [] vals = new int[Buckets];
    for (int i = 0; i < vals.Length; i++)
    {
        vals[i] = input / Buckets;
    }
    int remainder = input % Buckets;
    // give all of the remainder to the first value
    vals[0] += remainder;

    // If instead  you wanted to distribute the remainder evenly, 
    // priority to first
    for (int r = 0; r < remainder;r++)
    {
        vals[r % Buckets] += 1;
    }

It is worth pointing out that the double example may not be numerically stable in that certain input values and bucket sizes could result in leaking fractional values.
