        "squarefree part"
        SYNTAX: X = sfp(A)

        A is an expression whose value is an element of Z, Q, a univariate
        polynomial over Z, Q or Z/pZ (where p is a prime), a univariate
        monic polynomial over number fields or Galois-fields, or a univariate 
        rational function over Q.

        You can use nfon in order to compute the squarefree part of
        univariate polynomials over Z or Q over the number field, 
        specified by curnf. 
        
        X is assigned the squarefree part of A.


        Example 1: (correct)

                sfp(-280)


        Example 2: (correct)

                sfp(2/3*x)
