| | checks if the first argument is greater than the second (public member function) | | ------------------------------------------------------------------------------------- |

[edit] Notes

Unlike std::greater, std::ranges::greater requires all six comparison operators <, <=, >, >=, == and != to be valid (via the totally_ordered_with constraint) and is entirely defined in terms of std::ranges::less.
