Description

The list of methods to do Random Double are organized into topic(s).

Method

doublerandomDouble()
random Double 
return RANDOMIZER.nextDouble();
doublerandomDouble()
random Double 
return (double) randomLong() / Long.MAX_VALUE;
doublerandomDouble()
this method returns a random number n such that 0.0 <= n <= 1.0 
Random r = new Random();
return r.nextInt(1000) / 1000.0;
doublerandomDouble(double low, double high)
Returns a double value with a positive sign, greater than or equal to low and less than high.
Note: low limit is inclusive and high limit is exclusive.
The formula used in this method is:
randomDouble = Math.random() * (high - low) + low; (low: Inclusive, high: Exclusive) 
return Math.random() * (high - low) + low;
doublerandomDouble(double min, double max)
Generate a double in the given range. 
return min + random.nextDouble() * (max - min);
doublerandomDouble(double min, double max)
random Double 
return (min + Math.random() * (max - min));
doublerandomDouble(double min, double max)
random Double 
return Math.random() < 0.5 ? ((1 - Math.random()) * (max - min) + min)
        : (Math.random() * (max - min) + min);
doublerandomDouble(int min, int max)
random Double 
return min + (max - min) * random.nextDouble();
doublerandomDouble(int start, int end)
random Double 
if (start > end) {
    int t = start;
    start = end;
    end = t;
long scope = ((long) end - (long) start);
return rnGenerator.nextDouble() * scope + start;
double[]randomDoubleArray(final int mDimensionality)
random Double Array 
final Random random = new Random();
final double[] retVal = new double[mDimensionality];
for (int i = 0; i < retVal.length; i++) {
    retVal[i] = random.nextDouble();
return retVal;
