Push_Internal_Simplify - Texas Instruments TI-89 Developer's Manual

Appendix A: System Routines — Expression Evaluation /
Algebraic Simplification

push_internal_simplify

Declaration: void push_internal_simplify (EStackIndex i )
Category(ies): Expression Evaluation / Algebraic Simplification
Description: The low-level entry point to the simplifier accepts all valid tokenized
expressions and produces an internal tokenized expression.
Inputs: i
Outputs: Pushes onto the expression stack the internal tokenized form of the result
of evaluating / simplifying the input.
Assumptions: Input must be a logical, Boolean, or algebraic expression or relation. Use
push_simplify_statements to process TI-BASIC commands.
Side Effects: May expand expression stack, cause heap compression, or throw an error.
Availability: On AMS 2.01 and higher.

Example:
If i is the EStackIndex of the external-tokenized form of the complex expression a + b †
which is A_VAR_TAG B_VAR_TAG I_TAG MULTIPLY_TAG ADD_TAG, then
push_internal_simplify (i);
pushes the internal-tokenized form of the expression, which is
A_VAR_TAG B_VAR_TAG IM_RE_TAG.
