-The `*_real` types hold a floating-point degree value, so `count()` reads
-directly in scale degrees (e.g. `22.5`) and `std::format` renders them as
-`22.5°C`, honoring the standard float format spec (`{:.1f}` → `22.5°C`). Obtain
-one from an exact reading with a cast — see [Usage](#usage). The integer types
-format as their exact stored value with a precision-qualified unit (e.g.

+With `std::format`, `{}` renders a temperature as its exact stored value with a
+precision-qualified unit (e.g. `millicelsius{22500}` → `22500m°C`), while any
