>From my recent experience, I think you should :
 - define a default value for your properties in your content
interface :

    myFloatProperty1 = Float (..., default=0.0)
    myFloatProperty2 = Float (..., default=0.0)

 - define the "set_before_add" value in your browser package
"configure.zcml"

	<addform
		schema=".interfaces.IMyInterface"
		set_before_add="myFloatProperty1 myFloatProperty2"
		...
		/>

I think that this should do the job you're looking for.
