Concept definition

    template<class T>
    concept has_epsilon = is_op<T> and requires (const T& t) { t.epsilon; }

Detailed Description

Template Parameters

T	The type to be checked.

The has_epsilon concept is satisfied when T is a framework expression type (see is_op) with an epsilon member, like floating_point_constant and the floating-point specialisation of value<T>. The comparators treat the operands within this tolerance as equal; a custom comparator uses it to do the same.

The types of the application are excluded, even if they have a member named epsilon, so that they are compared with their own operators.

Only the deprecated floating-point wrappers have a tolerance, so the concept is deprecated with them, and is available only when MICRO_OS_PLUS_MICRO_TEST_PLUS_DEPRECATED_ENABLED is defined.

Deprecated

to be removed with the deprecated floating-point wrappers (since 6.0.0)
