tuple_acostuple_acosTupleAcosTupleAcos (Operator)


tuple_acostuple_acosTupleAcosTupleAcos — Compute the arccosine of a tuple.


tuple_acos( : : T : ACos)

Herror tuple_acos(double T, double* ACos)

Herror T_tuple_acos(const Htuple T, Htuple* ACos)

void TupleAcos(const HTuple& T, HTuple* ACos)

HTuple HTuple::TupleAcos() const

static void HOperatorSet.TupleAcos(HTuple t, out HTuple ACos)

HTuple HTuple.TupleAcos()


tuple_acostuple_acosTupleAcosTupleAcosTupleAcos computes the arccosine of the input tuple TTTTt. The arccosine is always returned as a floating point number in ACosACosACosACosACos. The angles in ACosACosACosACosACos are represented in radians. The arccosine of a string is not allowed.

Exception: Empty input tuple

If the input tuple is empty, the operator returns an empty tuple.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_acostuple_acosTupleAcosTupleAcosTupleAcos, which can be used in an expression in the following syntax:

ACos := acos(T)
