Remarks

Please note, that this filter can be concretized only with basic data types and structures of such types. Concretizing the filter with a non-comparable complex data type, such as Image or Region, will raise a Domain Error.

Using this filter to compare data of type Real (or structures with this type) may be tricky. It is caused by the fact that very small (unnoticeable) differences in values of such types may lead to unpredictable negative results in comparison of these values.
