double

min()

List

toList()
Converts this array to a List of the same size, with each element added to the list. 
Set

toSet()

String

toString()
Returns the string representation of the given array. 
Coerces a double array to a boolean value. A double array is false if the array is of length 0, and true otherwise.
Calculates the average of the doubles in the array.
assert 5.0d == ([2,4,6,8] as double[]).average()
Checks whether the array contains the given value.
value
 the value being searched forCounts the number of occurrences of the given value inside this array.
Comparison is done using Groovy's == operator (using
compareTo(value) == 0
or equals(value)
).
value
 the value being searched forReturns a sequential DoubleStream with the specified array as its source.
Stream
for the arrayFlatten an array. This array and any nested arrays or collections have their contents (recursively) added to the new collection.
Support the subscript operator with an IntRange for a double array
range
 an IntRange indicating the indices for the items to retrieveSupport the subscript operator with an ObjectRange for a double array
range
 an ObjectRange indicating the indices for the items to retrieveSupport the subscript operator with a range for a double array
range
 a range indicating the indices for the items to retrieveSupport the subscript operator with a collection for a double array
indices
 a collection of indices for the items to retrieveReturns indices of the double array.
Zips a double[] with indices in (index, value) order starting from index 0.
Zips a double[] with indices in (index, value) order.
offset
 an index to start fromConcatenates the string representation of each items in this array, with the given String as a separator between each item.
separator
 a String separatorAdds max() method to double arrays.
Example usage:
double[] nums = [1.1d, 2.2d, 3.3d] assert 3.3d == nums.max()
Adds min() method to double arrays.
Allows arrays to behave similar to collections.
Returns a sequential Stream with the specified array as its source.
Stream
for the arraySums the items in an array.
assert (1+2+3+4 as double) == ([1,2,3,4] as double[]).sum()
Sums the items in an array, adding the result to some initial value.
assert (5+1+2+3+4 as double) == ([1,2,3,4] as double[]).sum(5)
initialValue
 the items in the array will be summed to this initial valueSwaps two elements at the specified positions.
Example:
assert ([1, 3, 2, 4] as double[]) == ([1, 2, 3, 4] as double[]).swap(1, 2)
i
