ExactConstraint
the(int)42 == (long)42
would fail despite obvious implicit casting available if types were known.BaseType is often undefined. E.g. Attributes don't have a
datatype
in the XSD in the same way Psets canignoreCase = true
. E.g. "à rénover"=="A Renover"ignoreCase is clearly an extension to the standard, but this feels like a useful addition.
This is based on the algorithm at Testcase "[PASS] Floating point numbers are compared with a 1e-6 tolerance 1-4/4" buildingSMART/IDS#78 (comment)
This last one may need some discussion with other implementors as it introduces some subtleties, such as
42.00001 <= 42 : Constraint Satisfied - despite being > 42
42.00001 > 42 : Constraint Satisfied - as expected
