from hp50g expression 2 latex

[peacecalc]

Next try:

\[ \frac{\sqrt{a+\left(b-c\right)\cdot cos\left(\frac{4}{d}\right)}\cdot \left(7+e\right)^{\frac{f}{g-h}}}{5\cdot \left(\left(x\right)^{3}-\left(x\right)^{a}\right)\cdot ln\left(2\cdot y\right)\cdot \left(e\right)^{\frac{\left(x\right)^{2}-7\cdot x}{5}}} \]

Is that worth going on or it's not very useful?

Code:

\frac{\sqrt{a+\left(b-c\right)\cdot cos\left(\frac{4}{d}\right)}\cdot \left(7+e\right)^{\frac{f}{g-h}}}{5\cdot \left(\left(x\right)^{3}-\left(x\right)^{a}\right)\cdot ln\left(2\cdot y\right)\cdot \left(e\right)^{\frac{\left(x\right)^{2}-7\cdot x}{5}}}

I implemented uppercase letters are change to lowercase. Because typing in HP 50g is easier with capitals, but normally in mathematical expressions are used lowercase letters (not always I know). Because my program is only analyzing one sign after the other, I have no change to distinguish between "e^x" and "(7+e)^x", so I always get the basis with parenthesis. The MATCH command eliminates double parenthesis always, the equation writer, too. The asterix "*" is replaced by "\cdot".
You have then more multiplication dots as required by mathematical conventions, but nevertheless the expression is correct.
The double backslash: I haven't any idea for a workaround (only with the replace function of an editor). If you transfer binary the result you get a chinese code on win 7.
