That's a large class of applications. One of our known users is a trading firm and the majority of their use is add/sub/mul/div and conversion to/from text via `to_chars` and `from_chars`. Not only are we able to do these text conversions exactly we can do it fast since we have deep familiarity with the problem set: https://cppalliance.org/decimal/decimal.html#benchmarks_charconv.
