test numeric value as input for issue #99

[rngadam]

Try to add a test to demonstrate and possibly fix issue #99. The test fails but I don't understand why...

$ rspec
.....................F[deprecated] I18n.enforce_available_locales will default to true in the future. If you really want to skip validation of your locale you can set I18n.enforce_available_locales = false to avoid this message.
Translated 5 keys

Could you change it to just the test?
