"$" ("$$" to be exact) is actually used in TeX to indicate opening and closing of statements/mathematical expressions. I think the author of this project is trying to conform to TeX syntax as much as possible so that TeX users like me would feel at home :).
- pflats 10y ago>"$" ("$$" to be exact) is actually used in TeX to indicate opening and closing of statements/mathematical expressions. Both are used. A single $ is used for inline math, the double $$ begins an equation on its own line. For example: The solution to $ax^2 + bx + c = 0$ will be $$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$ The first block will be mid-sentence, while the second one will get its own line.
- widdma 10y agoThe story is that Knuth chose '$' to denote math mode because math typesetting at the time was prohibitively expensive.
- stuffedBelly 10y agoahaha, that's a good piece of anecdote.
- wangchow 10y agoAh, wasn't aware of that. Thanks. :)
