feat(floats): support floats as the minimum ratio

[timsawtellgo1]

Support a float as the minimumRatio value. In our codebases, the minimum value we can use now is 1%, and that is too high off a difference for us. We would like to support a minimum ratio of something like 0.2%.

Merging and will build a new version in a minute
