push_independent_terms

Declaration: void push_independent_terms (EStackIndex i , EStackIndex var )
Category(ies): Algebra Utilities
Description: Pushes onto the estack the sum of all syntactic terms of the expression
indexed by i that are independent of the variable or kernel indexed by var .
If there are no independent terms, pushes Float0 if IS_ARITH_APPROX is
true and Integer0 if IS_ARITH_APPROX is false.
Inputs: i
var — Index of the top tag of an internally-simplified variable or kernel.
Outputs: None
Assumptions: None
Side Effects: None
Availability: On AMS 2.02 and higher.

Example:
push_quantum (PI_TAG);
k = top_estack;
push_quantum (8u);
replace_top2_with_sum (k);
k = top_estack;
push_quantum (9u);
j = top_estack;
push_ln (j);
replace_top2_with_sum(j);
replace_top2_with_sum(k);
k = top_estack;
push_quantum (9u);
push_independent_terms (k, top_estack);
