tuple_atan2tuple_atan2TupleAtan2TupleAtan2 (Operator)


tuple_atan2tuple_atan2TupleAtan2TupleAtan2 — Compute the arctangent of a tuple for all four quadrants.


tuple_atan2( : : Y, X : ATan)

Herror tuple_atan2(double Y, double X, double* ATan)

Herror T_tuple_atan2(const Htuple Y, const Htuple X, Htuple* ATan)

void TupleAtan2(const HTuple& Y, const HTuple& X, HTuple* ATan)

HTuple HTuple::TupleAtan2(const HTuple& X) const

static void HOperatorSet.TupleAtan2(HTuple y, HTuple x, out HTuple ATan)

HTuple HTuple.TupleAtan2(HTuple x)


tuple_atan2tuple_atan2TupleAtan2TupleAtan2TupleAtan2 computes the arctangent of the input tuples YYYYy/XXXXx while treating all four quadrants correctly. The arctangent is always returned as a floating point number in ATanATanATanATanATan. The angles in ATanATanATanATanATan are represented in radians. The arctangent of a string is not allowed.

Exception: Empty input tuples

If either or both of the input tuples are empty, the operator returns an empty tuple.

HDevelop In-line Operation

HDevelop provides an in-line operation for tuple_atan2tuple_atan2TupleAtan2TupleAtan2TupleAtan2, which can be used in an expression in the following syntax:

ATan := atan2(Y, X)
