Name
tuple_sgntuple_sgnTupleSgnTupleSgn — Calculate the sign of a tuple.
Herror tuple_sgn(double T, Hlong* Sgn)
Herror T_tuple_sgn(const Htuple T, Htuple* Sgn)
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
HDevelop provides an in-line operation for tuple_sgntuple_sgnTupleSgnTupleSgnTupleSgn,
which can be used in an expression in the following syntax:
Sgn := sgn(T)
- Multithreading type: independent (runs in parallel even with exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
TTTTt (input_control) number(-array) → HTupleHTupleHtuple (real / integer) (double / int / long) (double / Hlong) (double / Hlong)
Input tuple.
Signs of the input tuple as integer numbers.
