Dear gepo, you may simulate huge exponents per hand using additional dummy variables as follows: Code: ring R = 0, (x100, x50, x), lp; // ADD dummy variables for multiples qring Q = groebner( ideal( x100 - x50^2, x50 - x^50 ) ); // Relations between x^n and x_n poly H = x100 * x100 - x50 + x; // bigger exponents H; // x100^2-x50+x NF(H, std(0)); // or use subst to get expression in 'x' x^200-x^50+x
I hope this helps, Oleksandr
Dear gepo,
you may simulate huge exponents per hand using additional dummy variables as follows:
[code] ring R = 0, (x100, x50, x), lp; // ADD dummy variables for multiples qring Q = groebner( ideal( x100 - x50^2, x50 - x^50 ) ); // Relations between x^n and x_n poly H = x100 * x100 - x50 + x; // bigger exponents H; // x100^2-x50+x NF(H, std(0)); // or use subst to get expression in 'x' x^200-x^50+x [/code]
I hope this helps, Oleksandr

The limit for exponent can be extended up to the size that of the type long, i.e. up to 2^63 on 64-bit machine - this will be available in one of the next versions. There no plans to go to larger exponent as this would require a change of the data structures for polynomials.

What I found was Singular can only support at most x^(2^30) (on a 64-bit machine). Now I am wondering whether there is a way to support large exponent, like x^(2^256). Or whether Singular has a plan to support large exponent.
Thanks in advance. Gepo
