Adder

As the name suggests, adders are control elements capable of summing any number of real values.

The number of inputs, as well as their signs, are defined by the user, as shown in the figure below.

In its single field "Signs", a list of signs separated by spaces is entered, containing the symbols “+” for a positive input and “-” for a negative input.

Information

The user can insert two or more input signs in the block.

Once new inputs are added, corresponding nodes will be included in the graphical element of the adder, which can then be connected through connection lines.

Similarly, the user may remove pre-existing input signs, which will be removed from the graphical icon by deleting the node and the line (if one is connected).
