[XeTeX] Local changes to mathmode digits

[Vafa Khalighi]

Sure. Check xepersian package documentation on page 42 for

 \DefaultMathsDigits \PersianMathsDigits \AutoMathsDigits

xepersian-mathsdigitspec achieves this using \everymath and \everydisplay primitives. Note that xepersian-mathsdigitspec for this feature to work relies on \if at Latin conditional of bidi package. polyglossia does not know about this so you may have to do some adjustments, i.e. \if at Latin should be true inside non-RTL script and false inside RTL script.

Is there anyway to change the math mode digits for only certain parts of 
a text?

I have some math in Arabic text in a largely English document. I would 
like to change the math mode digits in this parts to use Eastern Arabic 
digits, whereas the rest of the text will use standard Hindu-Arabic digits.

For an entire document, I can use

\usepackage{xepersian-mathsdigitspecarab}
\setdigitfont[Mapping=arabicdigits]{Arabic Font}

to change the digits, but is there anyway I can just make this active 
for certain parts of the overall document?


Thanks,

Nathan
