push_constant_factors

Declaration: void push_constant_factors (EStackIndex k )
Category(ies): Algebra Utilities
Description: Pushes onto the estack the product of all syntactic factors of the
expression indexed by k that do not contain variables.
If there are no constant factors, pushes Float1 if IS_ARITH_APPROX is
true and Integer1 if IS_ARITH_APPROX is false.
Inputs: k — Index of the top tag of an internally-simplified algebraic expression.
Outputs: None
Assumptions: None
Side Effects: None
Availability: All versions of the TI-89 / TI-92 Plus.
