Vectors are used for providing numerical values. There are different types of vectors (e. g. position vectors, range vectors or property vectors for RGB colors). The type of a vector (and optionally information in the root-element) gives the domain and the number of the elements that it contains. Each vector element is either a number or a variable, which is set in the Fib object above the Fib element of the vector.

If the value of an evalued element is outside of its domain (the domain for the vector element), this value is rounded to the nearest value that lies in the domain. If an element of the vector is not existing, it is evaluated as the zero value of its domain.

Vectors of one type are only used in a very specific type of Fib element.

A listing of the possible vector typs can be found in Table 1 .
