Hi
Is there way, that when I export and org file with a table, its content
is rounded when exported to html/latex?

The exporters take the text to be exported from the buffer, so if the buffer contains
arbitrary precision, then I don't think so: you'd have to apply a filter of some sort.
It's easy enough however to set the format for calc, recalculate all the tables, export,
then reset the format and recalculate once more to get back to where you were. Note
that internally org calculates floating point numbers to 12 decimal places (roughly)
but displays only 8 of them (to keep the display a bit more compact). See
(info "(org) Formula Syntax for Calc")
for details. Here's an example to use fixed-point format with 3 decimals:
--8<---------------cut here---------------start------------->8---
* Set floating point format to fixed point with 3 decimals :noexport:
#+begin_src emacs-lisp
(setq org-calc-default-modes '(calc-internal-prec 12 calc-float-format
(fix 3) ;;; the default here was (float 8)
calc-angle-mode deg calc-prefer-frac nil calc-symbolic-mode nil calc-date-format
(YYYY "-" MM "-" DD " " Www
(" " hh ":" mm))
calc-display-working-message t))
#+end_src
* Table
| x | log(x) |
|----+--------|
| 1 | 0 |
| 2 | 0.693 |
| 3 | 1.099 |
| 4 | 1.386 |
| 5 | 1.609 |
| 6 | 1.792 |
| 7 | 1.946 |
| 8 | 2.079 |
| 9 | 2.197 |
| 10 | 2.303 |
#+TBLFM: $2 = log($1)
--8<---------------cut here---------------end--------------->8---
