You do not *need* to uninstall TeXLive.  ConTeXt Standalone can work side
by side and it's very simple to install
<http://wiki.contextgarden.net/ConTeXt_Standalone>.  You can pick to use
the standalone for some of your compilations.

\persiandecimals and \arabicdecimals are very similar.  The difference is
(almost) only in digits for 0,4,5,6.  However, Ibn Saeed most probably
needs \arabicdecimals to typeset "mashiriqi" numerals.

The important thing is that neither one exists in TeXLive Context.  It was
there in MkII but not in MkIV for some reason.  It was added to MkIV
sometime in the fall.
