email on the user mailing list for details on how this bug manifests.
Implementation choice background:
* If the number were to be saved as a number then {{4.2}} could be considered
either as a float or as a double and hence the normalizer classes would need
setters for both those possibilities. Equally, {{42.0}} could be saved as just
{{42}} which then could be either an int or a long and so again setters for
both possibilities would be needed. All this complexity is avoided by saving
the number as a string. The class has convenience float setters which can be
handy for use in tests.
