did_push_approx_inflection_point

Declaration: Boolean did_push_approx_inflection_point (EStackIndex i ,
EStackIndex vi , Float a , Float b )
Category(ies): Math
Description: Returns TRUE if it pushed an approximate inflection point of the expression
indexed by i with respect to the variable indexed by vi between lower
bound a and upper bound b .
Inputs: i
vi
a , b — Float bounds with a < b.
Outputs: Returns TRUE if it pushed an approximate inflection point of the expression
indexed by i with respect to the variable indexed by vi between lower
bound a and upper bound b . Otherwise returns FALSE.
Assumptions: None
Side Effects: None
Availability: On AMS 2.02 and higher.

Example:
/* Returns TRUE after pushing tagged float 0.0 onto top of the estack. */
push_quantum_as_nonnegative_int (3u);
push_quantum (8u);
vi = top_estack;
push_quantum (EXPONENTIATION_TAG);
