Appendix A: System Routines - Expression Evaluation / Algebraic Simplification 541 NG_execute Declaration: void NG_execute (HANDLE hExpr, BOOL bApprox) Category(ies): Expression Evaluation / Algebraic Simplification Description: Executes one or more expressions or statements. Inputs: hExpr - HANDLE of memory containing expression(s) or statement(s) to execute. bApprox - NG_APPROXIMATE approximates the result. NG_DONT_APPROXIMATE uses the current mode setting. Outputs: Depending upon the input, may push evaluation result on estack in external tokenized form. The evaluation of an algebraic expression or a function leaves a result on the estack. The execution of commands or programs does not leave a result on the estack. Assumptions: None Side Effects: Clears error context, resets control flags, may cause estack expansion, heap compression, or throw errors. Availability: All versions of the TI-89 / TI-92 Plus. TI-89 / TI-92 Plus Differences: None See Also: None Example: If h is the HANDLE of memory containing a tokenized form of the statement Define f(x) = sin(x) then NG_execute (h, NG_DONT_APPROXIMATE); would define the function f in the current symbol table and would not leave any result on the estack.
