tuple_sgntuple_sgnTupleSgnTupleSgn (Operator)


tuple_sgntuple_sgnTupleSgnTupleSgn — Calculate the sign of a tuple.


tuple_sgn( : : T : Sgn)

Herror tuple_sgn(double T, Hlong* Sgn)

Herror T_tuple_sgn(const Htuple T, Htuple* Sgn)

void TupleSgn(const HTuple& T, HTuple* Sgn)

HTuple HTuple::TupleSgn() const

static void HOperatorSet.TupleSgn(HTuple t, out HTuple sgn)

HTuple HTuple.TupleSgn()


tuple_sgntuple_sgnTupleSgnTupleSgnTupleSgn calculates the sign of the elements of the input tuple TTTTt and returns them as integer numbers (-1,0,1) in the output tuple SgnSgnSgnSgnsgn. The calculation of the sign 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
