30.03.2008

This header contains logical predicates for value comparison, analogous to std::less, std::greater and others. The main difference from the standard equivalents is that the predicates defined in this header are not templates and therefore do not require a fixed argument type. Furthermore, both arguments may have different types, in which case the comparison is performed without type conversion.

	Note
	In case if arguments are integral, the conversion is performed according to the standard C++ rules in order to avoid warnings from the compiler.

namespace boost {
  namespace log {
    struct equal_to;
    struct greater;
    struct greater_equal;
    struct less;
    struct less_equal;
    struct not_equal_to;
  }
}
