示例1: Percentile
private double Percentile(IOrderedEnumerable<double> sortedData, double p)
{
int count = sortedData.Count();
if (count == 0) return 0;
if (count == 1) return sortedData.Last();
if (p >= 100.0d) return sortedData.Last();
double position = (count + 1) * p / 100d;
double leftNumber, rightNumber;
double n = p / 100d * (count - 1) + 1d;
if (position >= 1)
{
leftNumber = sortedData.ElementAt((int)Math.Floor(n) - 1);
rightNumber = sortedData.ElementAt((int)Math.Floor(n));
}
else
{
leftNumber = sortedData.First();
rightNumber = sortedData.ElementAt(1);
}
if (Math.Abs(leftNumber - rightNumber) < Double.Epsilon)
return leftNumber;
else
{
double part = n - Math.Floor(n);
return leftNumber + part*(rightNumber - leftNumber);
}

public HighChart ParseToHighChart(IOrderedEnumerable<ScoreList> source)
{
var hiChart = new HighChart();
if(source.Any())
{
hiChart.Name = source.First().Title;
hiChart.Data = source.Select(s => ParseDateAndNumber(s.Date, s.Popular)).ToList();
}
return hiChart;
}示例3: findCloserKey
private int findCloserKey(int value, IOrderedEnumerable<int> keyNumbers)
{
return keyNumbers.First(number => number <= value);
}示例4: AddCorners
private void AddCorners(IOrderedEnumerable<Pixel> cornerCandidates)
{
if (cornerCandidates.Count() > 50)
{
//First and Last point are corners
MassureAngleAndAddCorner(cornerCandidates.First());
MassureAngleAndAddCorner(cornerCandidates.Last());
}
else
{
// middle point is corner
int index = cornerCandidates.Count() / 2;
MassureAngleAndAddCorner(cornerCandidates.ElementAt(index));
}
