hi. question?

Hi heureka!

as DavidQD pointed out, this problem is a result of the calculation precision of the internal calculation algorithms. The configured precision for each function (factorial, sin, cos, sqrt..)  is a trade-off between accurancy and server costs.

I was able to configure a much higher precision for the factorial function because of some new powerful servers. (for factorial inputs below 199!)

> (23-1)! mod 23 must be 22 ( or -1).

this should be now improved as well

Thank you very much for your feedback, I really appreciate it!

btw: a automatic image sizing feature will be availabe soon

I can confirm that this is a bug that will be fixed in the near future, but you can use this input: ncr(718, 6)

$${\left({\frac{{\mathtt{718}}{!}}{{\mathtt{6}}{!}{\mathtt{\,\times\,}}({\mathtt{718}}{\mathtt{\,-\,}}{\mathtt{6}}){!}}}\right)} = {\mathtt{186\,345\,070\,770\,859}}$$

why not?           

$$\underset{\,\,\,\,{\textcolor[rgb]{0.66,0.66,0.66}{\rightarrow {\mathtt{vater, sohn, mutter, tochter}}}}}{{solve}}{\left(\begin{array}{l}{\mathtt{vater}}={\mathtt{1.4}}{\mathtt{\,\times\,}}{\mathtt{sohn}}\\
{\mathtt{mutter}}={\frac{{\mathtt{sohn}}}{{\mathtt{2}}}}\\
{\mathtt{tochter}}={\frac{{\mathtt{mutter}}{\mathtt{\,\times\,}}{\mathtt{2}}}{{\mathtt{3}}}}\\
{\mathtt{vater}}{\mathtt{\,\small\textbf+\,}}{\mathtt{sohn}}{\mathtt{\,\small\textbf+\,}}{\mathtt{mutter}}{\mathtt{\,\small\textbf+\,}}{\mathtt{tochter}}={\mathtt{9\,700}}\end{array}\right)} \Rightarrow \left\{ \begin{array}{l}{\mathtt{vater}} = {\mathtt{4\,200}}\\
{\mathtt{sohn}} = {\mathtt{3\,000}}\\
{\mathtt{mutter}} = {\mathtt{1\,500}}\\
{\mathtt{tochter}} = {\mathtt{1\,000}}\\
\end{array} \right\}$$

Hallo radix,
