Push_Poly_Qr - Texas Instruments TI-89 Developer's Manual

Appendix A: System Routines — Math

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.
i , j
Inputs:
gv
choice — One of PUSH_QUOTIENT, PUSH_REMAINDER, or
Outputs: The index of the first expression pushed.
Assumptions: None
Side Effects: None
Availability: On AMS 2.02 and higher.

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);
replace_top2_with_pow (exponent);
add1_to_top ();
i = top_estack; /* i -> x^2 + 1 */
push_quantum (8u);
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);
