tuple_sgntuple_sgnTupleSgnTupleSgnTupleSgntuple_sgn calculates the sign of the elements of the input tuple TTTTtt and returns them as integer numbers (-1,0,1) in the output tuple SgnSgnSgnSgnsgnsgn. 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_sgnTupleSgnTupleSgnTupleSgntuple_sgn, which can be used in an expression in the following syntax:

Sgn := sgn(T)
