Replacing Western Arabic numerals with Arabic–Indic numerals in formulas

Question

Is there a way to use non-Western Arabic digits in formulas of an English tex document? For example in output of

$$\frac{100x}{25}$$

Arabic–Indic numerals/Eastern Arabic digits (٠ ١ ٢) will appear instead of Western Arabic (0, 1, 2) ones. I'm looking for a way workable with latex without using xetex.

Don't use $$...$$. Use \[...\] instead ;-). Far more important question: What are English digits? — , Mar 25 '15 at 17:20
See http://tex.stackexchange.com/questions/503/why-is-preferable-to for the $$...$$ issue — , Mar 25 '15 at 17:22
This question is misleading. We tend to name 1,2,3 etc as arabic digits, not as English digits — , Mar 25 '15 at 18:25
I agree with @SoundsOfSilence that the wording is misleading. The Hindu-Arabic numeral system was adopted in Europe in the 12th century when al-Khwarizmi's book "Algebra" was translated and so the numbering became known as "Arabic numerals" (as opposed to "Roman numerals") which causes confusion. Perhaps it would be clearer if you replace "English digits" with "Western Arabic numerals" and "Arabic ones" with "Arabic–Indic numerals" or "Eastern Arabic numerals" for clarity. — Nicola Talbot, Mar 25 '15 at 18:54
Well I do not know what is an exact name for arabic and english digits. btw, if you edit my question I'll accept. — Minimus Heximus, Mar 25 '15 at 19:11
Okay. I'll edit it. It may help other users with the same question when they search the site. — Nicola Talbot, Mar 25 '15 at 19:33
BTW I didn't mean to sound like I was giving a lecture. I just wanted to explain why the terms "english digits" and "arabic ones" were causing confusion. :-) — Nicola Talbot, Mar 25 '15 at 19:48

You could use lualatex:

%!TEX TS-program = lualatex
\documentclass{article}

\usepackage{fontspec}
    \setmainfont{Times New Roman}
%   \newfontfamily\arabicfont[Script=Arabic,Numbers=Arabic]{Arial Unicode MS}

\begin{document}
test 
\[\ell+\frac{١٠٠x}{٢٥}\]
\end{document}

But I do not know how to use a specific font for the Arabic. Simply enclosing the numbers in \arabicfont(defined in preamble) does not seem to work in the environment.
