Just check for decimals instead of exactly 3

jnunemaker · jnunemaker · commit c56f990b467c · 2016-08-01T10:48:25.000-04:00
When checking 3 explicitly we sometimes get failures because 1.1.to_s is "1.1" instead of "1.10".

According to vmg, one or more should be fine and we want more than 2 points of precision, so it is better to change the test than the implementation.
