Answer types
There are two levels for setting the type of answers in a question: at the question level, with a uniform type for all answers in the question, or within each answer environment. Hence a question can for instance wrap an answer of type Multiple Choice and an other one of typy Input Fields.
There are Multiple Choice problems of different types: unique, multiple, yesno, .... For details see the corresponding paragraph below. Do not confuse the term "type of MCproblems" with the term "type of answers".
(see Different Answer Type)
Setting the type is done by the \type{...}
command, and the position of the command determines
how it works.
Example 1 (one type for all answers fields):
1 2 3 4 5 6 7 8 9 10 11 12  \begin{question}
\type{input.number} % set for all answers
\begin{answer}
...
\end{answer}
\begin{answer}
...
\end{answer}
\end{question}

Example 2 (possibly different types for each answer):
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19  \begin{question}
\type{input.generic} % optional
\begin{answer}
\type{input.number} % this answer has to be a number
...
\end{answer}
\begin{answer}
\type{input.function} % this answer is a function
...
\end{answer}
\begin{answer}
\type{mc.multiple} % this answer block consists of a MCquestion.
...
\end{answer}
\end{question}

In the second example, the command \type{input.generic}
can be omitted, but each answer
environment needs to have a \type{...}
command. It is not possible to set a specific type
on question level and just overwrite it for some answers.
Notice that some features like [\permuteAnswers](input.fields.md#permutableanswers) won't be available if a question has different types of answers.

Here is just an overview of the types:
Type 
Preview 
input.number
example and detailed explanation 

input.finitenumberset
example
By default only numbers (e.g. 1, 5, 1.2, 2/3) are accepted values for the user input. With the command \allowForInput the set of valid symbols for the input can be extended. That allows for example to ask for multiple of pi: \allowForInput{+  * / pi} . 

input.function Compare the user's answer numerically with the pregiven solution or subject to given conditions
example and detailed explanation 

input.cases.function Designed for case differentiations of e.g. absolute value functions. Note that you can only use this input type in an answer environment.
example and detailed explanation 

input.interval By default only numbers (e.g. 1, 5, 1.2, 2/3) are accepted values for the user input. With the command \allowForInput the set of valid symbols for the input can be extended. That allows for example to ask for multiple of pi: \allowForInput{+  * / pi} .
example and detailed explanation


input.matrix If the solution to a question is a row vector, a column vector or a matrix, the generic problem is of the type input.matrix.
example (cross product) and detailed explanation
Use checkAsFunction for comparing matrices with (multivariate) functions as matrix entries.
example (Jacobian matrix) 

input.text
examples and detailed explanation 

input.truthtable The boolean values can be changed by mouse click
example and detailed explanation
