NG_rationalESI |
Function (ROM Call 0x25F) |
Evaluates an expression in "EXACT" mode.
NG_rationalESI executes the entry on the expression stack pointed to by ptr
(it needs to point to the entry tag) in "EXACT" mode, then pushes the result (i.e. a new
expression) on the top of the expression stack. See the example of usage given with
display_statements. The same notes given with
NG_approxESI are true with this command too.
Note: The expression must not contain TI-Basic statements.
For executing TI-Basic statements, use NG_execute. Also, this
command may cause expansion of the expression stack or heap compression, and may throw
various errors is something is wrong.
Uses: ER_catch, ER_success, ER_throwVar, NG_control, push_simplify, ROM Call 0x5C7
