Comment:

 OK, let's use `std::from_chars()` where it supports `double` and postpone
 the rest.  With a suitable platform and toolchain that means only
 `getenv()` is a concern (and it seems perhaps it's fine on many platforms,
 it's just that POSIX allows it to return its value in a static buffer; or
 possibly concurrent `setenv()` might be problematic too?)
