A PrimitiveType defines a predefined DataType, without any substructure. A PrimitiveType may have algebra and operations defined outside of UML, for example, mathematically. Source Unified Modeling Language 2.5.1
UML DataType vs SysML ValueType Gallery Tutorial TRAIL: Webel's ultimate guide to Systems Modeling Language (v1) with MagicDraw/Cameo Section 08:02: The SysML ValueType, Unit, and using values Slide kind UML Profile Diagram
In SysML, unless you MUST use a DataType or PrimitiveType from an existing ModelLibrary or Profile, you SHOULD probably be using a ValueType, Enumeration ValueType, or SysML PrimitiveValueType instead so that it integrates with the value system of SysML.
A LiteralReal specifies a constant value of the PrimitiveType Real. Source Unified Modeling Language 2.5.1
A LiteralUnlimitedNatural specifies a constant value of the PrimitiveType UnlimitedNatural. Source Unified Modeling Language 2.5.1
A LiteralBoolean specifies a constant value of the PrimitiveType Boolean. Source Unified Modeling Language 2.5.1
A LiteralInteger specifies a constant value of the PrimitiveType Integer. Source Unified Modeling Language 2.5.1
A LiteralString specifies a constant value of the PrimitiveType String. Though a String is specified as a sequence of characters, String values are considered to be primitive in UML, so their internal structure is not specified as part of UML semantics. Source Unified Modeling Language 2.5.1
