Appendix A: System Routines - Algebra Utilities 275 push_dependent_terms Declaration: void push_dependent_terms (EStackIndex i, EStackIndex var) Category(ies): Algebra Utilities Description: Pushes onto the estack the sum of all top-level syntactic terms of the expression indexed by i that are dependent on the variable or kernel indexed by var. If there are no dependent terms, pushes Float0 if IS_ARITH_APPROX is true and Integer0 if IS_ARITH_APPROX is false. Inputs: i - Indexes the top tag of an internally-simplified algebraic expression. var - Indexes the top tag of an internally-simplified variable or kernel. Outputs: None Assumptions: None Side Effects: None Availability: On AMS 2.02 and higher. TI-89 / TI-92 Plus Differences: None See Also: push_independent_terms, push_constant_terms, push_nonconstant_terms, index_numeric_term Example: void push_dependent_terms (EStackIndex i, EStackIndex var) /* Pushes onto the estack the sum of all terms of the expression indexed by i that are dependent on the variable indexed by var. */ { if (ADD_TAG == ESTACK (i)) { push_dependent_terms (next_expression_index (--i), var); if (is_independent_of (i, var)) return; else add_to_top (i); } else if (is_independent_of (i, var)) push0 (); else push_expression (i); } TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
