Push_Greater_Than - Texas Instruments TI-89 Developer's Manual

Appendix A: System Routines — Expression Evaluation /
Algebraic Simplification

push_greater_than

Declaration: void push_greater_than (EStackIndex i , EStackIndex j )
Category(ies): Expression Evaluation / Algebraic Simplification
Description: Pushes onto the estack the internally-simplified equivalent of the inequality
(expression i ) > (expression j ).
To accommodate stepping through inequality solving, the simplification is
merely a comparison of the two sides for the default
IS_AUTO_SOLVE_OFF.
If the result is neither a TRUE_TAG nor a FALSE_TAG, the result could be
true for some values of the variables therein but false for other values.
Alternatively the simplification might not be powerful enough to determine
that the result is always true or always false.
Inputs: i , j — Indices of the top tags of internally-simplified strings, algebraic
Outputs: None
Assumptions: None
Side Effects: None
Availability: On AMS 2.02 and higher.
