According to https://yaml.org/spec/1.2/spec.html#id2804092, 123456e1 (without quotes) is not a float but a string because there is no sign after the “e”. Also note that PyYAML yields

>>> import yaml
>>> print(yaml.dump({"a": "123456e1"}))
a: 123456e1

Sorry, I quoted the wrong part of the YAML specs, and it is a bug in PyYAML.
