Changing PARI types |
I have used "ground" to round the coefficients of a polynomial to the nearest integers, however the type of the coefficients remains at 6 (probably real or complex). This means that rootsmod (GEN) cannot handle the polynomial (the error actually comes from factormod, which is used by rootsmod). Is it possible to change the type of the coefficients so that they can be handled by rootsmod? For example, can I do something like: settyp (H [i], 1); for each coefficient, or would this be horribly dangerous?
