Thanks for joining james...

Either I have overlooked it or it is nowhere mentioned that data written/printed will be transformed and thereby lose precision. The R-bridge also sends data (double) different from those written by Zorro (float) in text files.I have now read more intensively about the topic and unfortunately there are many pitfalls, I would find it easier and better, if we can determine the precision.

Example:% f for floats% lf or something for doubles

How to print/write data with more precision?

I can't use printf, strf, file functions and so on or is that wrong - or is it possible and I'm just too stupid?
