UML-2.5.1: 'DataTypes model Types whose instances are distinguished only by their value'
The slide is adapted from UML-2.5.1 Figure 10.3 DataType Notation:

From Wikipedia:
A complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, satisfying the equation i2 = −1
SysML-1.6: 'A Complex value type represents the mathematical concept of a complex number. A complex number consists of a real part defined by a real number, and an imaginary part defined by a real number multiplied by the square root of -1 ...'
Note again this minor matter:
The SysML Complex "primitive" ValueType does in fact have substructure: realPart:Real and imaginaryPart:Real

  [UML-2.5.1] DataTypes model Types whose instances are distinguished only by their value
  [UML-2.5.1] A PrimitiveType defines a predefined DataType, without any substructure. A PrimitiveType may have algebra and operations defined outside of UML, for example, mathematically.
  [SysML-1.6] Value types may be used to type properties, operation parameters, or potentially other elements within SysML.
  [SysML-1.6] SysML defines ValueType as a stereotype of UML DataType to establish a more neutral term for system values that may never be given a concrete data representation.
  [UML-2.5.1] Features represent structural and behavioral characteristics of Classifiers.
  [SysML-1.6] A SysML ValueType may define its own properties and/or operations, just as for a UML DataType.
  [UML-2.5.1] A DataType is a kind of Classifier. DataType differs from Class in that instances of a DataType are identified only by their value. All instances of a DataType with the same value are considered to be equal instances.
  [UML-2.5.1] If a DataType has attributes (i.e., Properties owned by it and in its namespace) it is called a structured DataType. Instances of a structured DataType contain attribute values matching its attributes.
  [UML-2.5.1] Instances of a structured DataType are considered to be equal if and only if the structure is the same and the values of the corresponding attributes are equal.
