Appendix A: System Routines - Math 813 push_poly_qr Declaration: EStackIndex push_poly_qr (EStackIndex i, EStackIndex j, EStackIndex gv, Int choice) Category(ies): Math Description: According to choice, pushes onto the estack the remainder, and/or then the quotient of polynomial i divided by polynomial j, with respect to gv. Returns the index of the first expression pushed. Top-level calls should be made via the macros PUSH_POLY_QUOTIENT, PUSH_POLY_REMAINDER, or PUSH_POLY_REMAINDER_THEN_QUOTNT. Inputs: i, j - Indices of the top tags of internally-simplified polynomials, generalized to allow non-negative fractional exponents. gv - Indexes the top tag of an internally-simplified variable or kernel. choice - One of PUSH_QUOTIENT, PUSH_REMAINDER, or PUSH_BOTH. Outputs: The index of the first expression pushed. Assumptions: None Side Effects: None Availability: On AMS 2.02 and higher. TI-89 / TI-92 Plus Differences: None See Also: push_gcd_then_cofactors Example: /* Pushes a tagged integer 2, then the polynomial x + 1, then returns the index of the pushed tagged integer 2. */ push_quantum (2u); exponent = top_estack; push_quantum (8u); /* Push variable x */ replace_top2_with_pow (exponent); /* top_estack -> x^2 */ add1_to_top (); i = top_estack; /* i -> x^2 + 1 */ push_quantum (8u); /* Push variable x */ subtract1_from_top (); j = top_estack; /* j -> x + 1 */ push_quantum (8u); gv = top_estack; /* gv -> variable x */ push_poly_qr (i, j, gv, PUSH_BOTH); TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
