Minecraft wiki entry for Infdev_20100327_to_Beta_1.7.3, associated text: While most of these values have can be ignored, it can indeed be seen that the low and high noise increment by 171.103 each block, or 684.412 each sampling at four blocks; dividing 2,147,483,648 by this will indeed result in the value 12550824 being returned. Similar results can be seen for selector noise and therefore Farther Lands, and using the maximum signed 64-but integer instead of 2,147,483,648 provides the Fartherer and Farthest Lands distances. (Depth noise far lands are dwarfed by low and high noise overflowing and are impossible to see unless depth noise is made to overflow beforehand.)
