 Dear Hans,
 Hello

 Thank you very much for your reply.
 A math formula In Persian language is exactly the same as in English
language except that the
 digits should be written in Persian. So what I want to do is to
replace the English digits with
 Persian digits in a math formula. However, with your code not only
the formula is right aligned, but
 also the square root symbol is mirrored.

 By the way, I couldn't find "bidi-001.tex" on ConTeXt Site, would you
please let me know where can
 I get it?

 Thanks,
 Mingranina
