Re: pattern example


Hi 

It works in  8.0.1 Windows7 too

In[1]:= f[3/5,4,5,2/3]/.f[x:(_Integer|_Rational)..]:>{x}

Out[1]= {3/5,4,5,2/3}

Hi Francisco,

I can't check on 8.0.1 right now, but both v8.0 and v7.0 give the result as
in the book.
I hope someone else will comment on 8.0.1.

Cheers,
Leonid
