Bug: Another possible error for in-line math parsing

Bug: Another possible error for in-line math parsing

[Jeff Horn]

Carsten et al,

Possible error when escaping dollar sign in inline-math. When using
the following org source:
------------------------------------------------------------------------------
Supposing $C_H=\$10$ and $C_L=\$20$.
...
$.30(\$50)+.70(\$20)=\$29$
------------------------------------------------------------------------------
The following LaTeX is produced upon publication:
------------------------------------------------------------------------------
Supposing \$C$_H$=\$10\$ and \$C$_L$=\$20\$
...
\$.30(\$50)+.70(\$20)=\$29$
------------------------------------------------------------------------------
Whereas the following LaTeX is expected:
------------------------------------------------------------------------------
Supposing $C_H=\$10$ and $C_L=\$20\$
...
$.30(\$50)+.70(\$20)=\$29$
------------------------------------------------------------------------------

Comparing the two different lines of source, I note that in the first
case the four inline math dollars are escaped when they should not be,
and two extra inline math dollars are inserted. In the second case,
all dollars are escaped correctly excepting the first inline math
dollar.

I'm obviously trying to use dollars as units in my math calculations.

Thanks for any help,

Jeff

BTW, I can confirm that this error does not occur in the block math
environment (wrapping the equations in escaped square brackets).

Additionally, the following source from org-mode:

`$.30(50)+.70(20)=29$`

Is not converted at all by MathJax.

Org-mode version 7.01trans, recent git pull from earlier this week.
Aquamacs on Snow Leopard.

Org-mode will never be a perfect TeX scanner, and this is really hard.
Help yourself and Org by using \( and \) as math delimiters when you  
wish to include dollar characters inside....

Ten-four. I'll try it when I get some time to go back and edit my
source files. Wonky use of dollar signs in math doesn't explain why
the following source doesn't work, though:

Thanks for the tip, though!

What does that mean?

The reason here is that $.30 looks too much like currency, and
Org tries hard to detect cases where is dollar in text is meant to
be currency and not math.  Here it fails, and also here you can use
\(...\).  In fact, using dollar makes parsing TeX *a lot* harder
in general.

:-)  

this is an expression from CB (citizen's band) radio days and means
"thanks" or "okay" or a combination of the two.  There's a whole
lexicon of 10-xx terms for fast communication over CB radio.
