std::less_equal

Defined in header <functional>

​

​

If the function call operator of the specialization std::less_equal<void> calls a built-in operator comparing pointers, it yields a strict total order even if the built-in operator<= does not.This strict total order is consistent among the specializations std::less<void>, std::greater<void>, std::less_equal<void>, and std::greater_equal<void>, and is also consistent with the partial order imposed by the corresponding built-in operators.

(since C++14)

The standard library provides a specialization of std::less_equal when T is not specified, which leaves the parameter types and return type to be deduced. less_equal<void> function object implementing x <= y deducing argument and return types (class template specialization)
