LongStream mapToDouble() in Java
LongStream mapToDouble() returns a DoubleStream consisting of the results of applying the given function to the elements of this stream.
Note : LongStream mapToDouble() is a intermediate operation. These operations are always lazy. Intermediate operations are invoked on a Stream instance and after they finish their processing, they give a Stream instance as output.

- DoubleStream : A sequence of primitive double-valued elements. This is the double primitive specialization of Stream.
- mapper : A stateless function to apply to each element.
Return Value : The function returns a DoubleStream consisting of the results of applying the given function to the elements of this stream.
