Singular Manual: addRat

| ##### 7.5.14.0. addRat Procedure from library `dmodloc.lib` (see dmodloc_lib). Usage: addRat(v,w); v,w vectors Assume: Assume that v,w have exactly two components, second ones not 0. Return: vector, representing rational function (v[1]/v[2])+(w[1]/w[2]) Note: Possibly present non-commutative relations of the basering are ignored. Example:
    LIB "dmodloc.lib";
    ring r = 0,(x,y),dp;
    vector v = [x,y];
    vector w = [y,x];
    addRat(v,w);
    ==> x2*gen(1)+xy*gen(2)+y2*gen(1)
    addRat(v,w) - [x2+y2,xy];
    ==> 0
