Note that for some kind of functions (e.g., hashes) this method will always return true. In particular, this default implementation always returns true.

public float defaultReturnValue()
Byte2FloatFunction
This default implementation just return the default null value
of the type (null
for objects, 0 for scalars, false for Booleans).
