Indeed, the marshal module uses repr() to encode floats in code objects.
The idea behind __repr__ seems prettly clear in the docs:
Called by the repr() built-in function and by string conversions
(reverse quotes) to compute the ``official'' string representation of
an object. If at all possible, this should look like a valid Python
expression that could be used to recreate an object with the same
value (given an appropriate environment). If this is not possible, a
string of the form "<...some useful description...>" should be returned.
The return value must be a string object. This is typically used for
debugging, so it is important that the representation is information-
rich and unambiguous.
