[Eric Pettersen]

When you define an attribute, ChimeraX needs to know what type its values are. It doesn't want to survey objects to discern the type. Since your setattr command used an integer value (0) to define the attribute, its type was guessed/assigned as int. You would either have needed to use a float to define it (0.0) or added "type float" to the setattr command.
