frac

frac R -- construct the fraction field of the ring R .

If R has no name yet, then the names for its symbols will be usurped as names for the corresponding elements of R . 

     i1 = F = frac (ZZ/101[x,y])
     
     o1 = F
     
     o1 : FractionField
     
     i2 = 1/x + 1/y + 1/2
     
          - 50 x y + x + y
     o2 = ----------------
                 x y
     
     o2 : F
