Many Korean tripartite (세벌식) keyboard layouts have a virtual numpad accessible with shift. In a particular layout I'm using [1] it is HJKL:YUIOP for 0 through 9, so you can type 3.141592 with shift plus L.J:JYPK. Note that most symbols from the numpad can also be typed with shift, and full stop and comma can be specifically typed with or without shift. To me it is much better than the ordinary numpad (even at the middle) because it only takes two rows instead of three rows.
