Current call to epsilon is made with the assumption that the dynamic type `content_type` is compatible with double. This does not hold true for numeric types that are bigger than double, e.g: `absl::uint128`. This CL fixes it by binding the call to `content_type`'s type.

Thanks, looks OK to me

Made a mistake with the author email used to commit in the other PR. The current PR uses the correct email with my employer domain. |

This looks good to me. epsilon for some custom integer type will be zero, so same behaviour as comparing to ~1e-16. It requires any content_type to have a numeric_limits specialisation but the header already requires that anyway.
This comparison to an unscaled epsilon looks dubious in general, but that's unrelated to the PR.
