Suppose you wanted to format a nifty math equation for insertion into plain old ordinary email, or maybe as a comment in your C program. For instance, something reasonably complex like this rendition of the series used in the BBP algorithm to compute hexidecimal digits of pi:
oo ===== __ \ / 4 2 1 1 \ -n || = > |------- - ------- - ------- - -------| 16 / \8 n + 1 8 n + 4 8 n + 5 8 n + 6/ ===== n = 0
It would be pretty tedious, right? Well, perhaps you could use this linke to aamath, a nifty command line program for rendering ascii art versions of math formulas.
