### 5.1.17 deg

`Syntax:`
  `deg (` poly_expression `)`
  `deg (` vector_expression `)`
  `deg (` poly_expression `,` intvec_expression `)`
  `deg (` vector_expression `,` intvec_expression `)`
`Type:`
  int
`Purpose:`
  returns the maximal (weighted) degree of the terms of a polynomial or a vector;
  deg(0) is -1.
  The optional second argument gives the weight vector, otherwise weight 1 is used for lex orderings and block ordering, the default weights of the base ring are used for orderings consisting of one block.

`Example:`

        ring r=0,(x,y,z),lp;
        deg(0);
      ==> -1
        deg(x3+y4+xyz3);
      ==> 5
        ring rr=7,(x,y),wp(2,3);
        poly f=x2+y3;
        deg(f);
      ==> 9
        ring R=7,(x,y),ws(2,3);
        poly f=x2+y3;
        deg(f);
      ==> 9
        vector v=[x2,y];
        deg(v);
      ==> 4
