# Polarity

A read-only connection. You can assign a tag or an expression to this connection. This connection determines whether a minus sign is shown. A minus sign is displayed when this connection has a positive non-zero value. If this connection is assigned, it overrides the polarity of the Value connection’s value.

If you assign an expression to this connection, the application calculates the value of the expression and uses the result to determine whether to show a minus sign.

If the Polarity connection uses a tag with a floating point address, values less than .5 will be rounded down and values greater than or equal to .5 will be rounded up.
