Random Double with a given Range

[Martin Pöpping]

Hello,

I´ve to implement an array which sum always have to 1.
In the API Documentation I´ve found Random.NextDouble(),
but it always returns a value x with 0.0 <= x < 1.0.

Is there a range to specify the random value a bit more?

I want to do it like this:

double[] myArray = new Array();

Random randomClass = new Random();

double random=0.0, currentValue=0.0, restValue=1.0;

for(int i = 0; i < myArray.Length; i++)
{
random=randomClass.NextDouble(0.0, restValue);
restValue -= random;
myArray[i]=restValue;
}

But this would only work if I would have a method like
NextDouble(double startValue, double endValue).

Do you have any ideas how to solve me problem?
Regards,

Martin

I solved my problem in a workaround.
