I would be very happy to have this package included in Fricas; I began to clean the code according to your comments. I also added a maximum number of iterations (in order to avoid infinite loops when requested precision is higher than current number of digits). Would you like me to include in my package an "algdep" function for guessing a polynomial from a numerical root (if any)? I encounter some problems while tring to convert some matrices to Matrix(Integer) type because I need to mix floats and integers in the computations, and I couldn't manage to coerce a rounded float to an integer type! How can I round a float to an integer in a compiled spad code? Best regards, tb. -- You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
