Declaration:
void
push_constant_terms
(EStackIndex
k
)
Category(ies):
Math
Description:
Pushes onto the estack the sum of all syntactic terms of the expression
indexed by
k
that do not contain variables.
If there are no constant terms, pushes Float0 if IS_ARITH_APPROX is
TRUE. Otherwise pushes Integer0.
Inputs:
k
— Index of the top tag of an internally-simplified algebraic expression.
Outputs:
None
Assumptions:
None
Side Effects:
None
Availability:
On AMS 2.02 and higher.

Example:
push_quantum (PI_TAG);
add1_to_top (); /* partial sum = top_estack */
push_quantum (8u); /* push variable x */
replace_top2_with_sum (foo); /* top_estack -> x + pi + 1 */
push_constant_terms (top_estack); /* Pushes pi + 1 */
