:mrdocs:

Set the length of this queue to the specified `newLength`. If `newLength` is less than the current length, elements at index positions at or above `newLength` are removed. Otherwise any new elements (at or above the current length) are initialized to the specified `initialValue`, or to 0.0 if `initialValue` is not specified. The behavior is undefined unless `0 <= newLength`.
