sh:minInclusive not evaluated correctly

[ulitol97]

I'm attempting to validate some RDF data thtough a SHACL schema. When setting a minimum-inclusive limit on a decimal quantity, it behaves as an exclusive limit.

For example, sh:minInclusive 18; does not validate for 18, the error message itself being contradictory:
LiteralValue("minInclusive violation. Expected 18 >= 18")

Example data used:

• RDF

@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix ex:      <http://example.org/> .

ex:reading a ex:sensorReading ;
          ex:readingTemperature "18"^^xsd:decimal .

• Shapes Graph

@prefix sh: <http://www.w3.org/ns/shacl#> .
@prefix xsd: <http://www.w3.org/2001/XMLSchema#> .
@prefix ex:      <http://example.org/> .

# Filters of a valid sensor reading
ex:ValidReading a sh:NodeShape ;
                sh:targetClass  ex:sensorReading ;
      			sh:property [
    				sh:path     ex:readingTemperature ;
                    sh:datatype xsd:decimal ;
                    sh:minInclusive 18;
  				] .

I fixed it by changing the following in the shapes graph:

• sh:minInclusive 18 to sh:minInclusive 18.00

Still, I did not expect that behaviour and it does not happen using Jena-SHACL or TopQuadrant validators
