No problem, I encourage any and all requests for improvement! This applies equally to any of my mods, including those that were not originally mine!
Though I personally never use this feature myself (I've always just disabled it from the settings menu lol), I was able to implement the changes almost exactly as described, as a new per-player setting for the number of significant digits.
Defaults to 4, but can be set as low as 0 (no decimal places shown) or as high as 10 (which retains the previous behavior of printing as many digits as possible). Also slightly improved the output legibility, so it doesn't print raw bracketed values. Though it's still not quite as verbose as the example provided, they are at least consistent with each other.
Implemented in v1.0.2
