[XeTeX] changing font for numbers in math mode?

[David Cottenden]

Greetings,

I'm not very expert - so don't quiz me overly - but my understanding is 
that setmathrm changes the maths roman font, whereas by default the 
maths digits are drawn from the normal maths font. You can change which 
font the digits are drawn from with:

   \DeclareMathSymbol{0}\mathalpha{operators}{"30}
   \DeclareMathSymbol{1}\mathalpha{operators}{"31}
   \DeclareMathSymbol{2}\mathalpha{operators}{"32}
   \DeclareMathSymbol{3}\mathalpha{operators}{"33}
   \DeclareMathSymbol{4}\mathalpha{operators}{"34}
   \DeclareMathSymbol{5}\mathalpha{operators}{"35}
   \DeclareMathSymbol{6}\mathalpha{operators}{"36}
   \DeclareMathSymbol{7}\mathalpha{operators}{"37}
   \DeclareMathSymbol{8}\mathalpha{operators}{"38}
   \DeclareMathSymbol{9}\mathalpha{operators}{"39}

I've been using this for a year or two to replace Euler digits (which 
may have merits, but clearly don't match any text digits).

Hope that helps,

David
