you can also do something like this to accept blank separated 
input values on a single line.

import std.stdio : writeln, readln;
import std.string: split;
import std.conv: to;
import std.algorithm: each;

void main()     {
	double [] Arr;

	Arr = readln().split().to!(double[]);
	Arr.each!writeln();

}
