dp_ptozp, dp_prim

dp_ptozp(dpoly)

:: Converts a distributed polynomial poly with rational coefficients into an integral distributed polynomial such that GCD of all its coefficients is 1.

dp_prim(dpoly)

:: Converts a distributed polynomial poly with rational function coefficients into an integral distributed polynomial such that polynomial GCD of all its coefficients is 1.

distributed polynomial

• dp_ptozp() executes the same operation as ptozp() for a distributed polynomial. If the coefficients include polynomials, polynomial contents included in the coefficients are not removed.
• dp_prim() removes polynomial contents.
