Sign

Output the sign of the input

Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

This blocks computes the output y as sign of the input u: 

     1  if u > 0
y =  0  if u == 0
    -1  if u < 0

The Boolean parameter generateEvent decides whether Events are generated at zero crossing (Modelica specification before 3) or not.
