+modernize-use-std-numbers
+=========================
+
+Finds constants and function calls to math functions that can be replaced
+with c++20's mathematical constants from the ``numbers`` header and offers fix-it hints.
+Does not match the use of variables with that value, and instead,
+offers a replacement at the definition of those variables.

I’ve also extended the documentation slightly to explain the replacements a bit further.
