Having studied the article, I, the newest monk, still can't cipher how to print two floating-point numbers so they'll align On The Decimal, so the numbers may be added properly, pencilularly.
e.g., print 0.12345 and -123456.12
to align thusly (oh, please let my spaces be preserved!):
I know I'm not the only monk that seeks this. There is that other fellow in Andalusia.
