| #### D.13.6.31 parameterSubstitute Procedure from library `tropical.lib` (see tropical_lib). Usage: parameterSubstitute(f,N); f poly, N int Assume: f is a polynomial in Q(t)[x_1,...,x_n] describing a plane curve over Q(t) Return: poly f with t replaced by t^N Example:
    LIB "tropical.lib";
    ring r=(0,t),(x,y),dp;
    poly f=t2xy+1/t*y+t3;
    parameterSubstitute(f,3);
    ==> (t6)*xy+1/(t3)*y+(t9)
    parameterSubstitute(f,-1);
    ==> 1/(t2)*xy+(t)*y+1/(t3)
