Consider the case that the answer to a problem is an interval.

The solution is defined by a left boundary ([ for closed and ] for open), two semicolon separated numbers or variables,

and a right boundary (] for closed or [ for open).

Here is an example

123456789101112131415 `\begin{problem}`

` `

`\begin{question}`

` `

`\text{Write down the Interval from 1 to 3:}`

` `

`\explanation{Test test Test}`

` `

`\type{input.interval}`

` `

`\field{rational}`

` `

`\begin{answer}`

` `

`\text{ A = }`

` `

`\solution{[1;3]} % or ] for open type, the boundaries should be separated by ";"`

` `

`\end{answer}`

` `

`\end{question}`

`\end{problem}`

There is the optional TeX command `\allowIntervalUnionsForInput[<boolean, default: true>]`

with which you can enable

the option that the student's answer can be given by the union of multiple intervals.

12345 `\begin{answer}`

` `

`\text{input.interval: $[1;4) = $}`

` `

`\allowIntervalUnionsForInput`

` `

`\solution{[1;4)}`

`\end{answer}`

Furthermore as an author you can give the correct solution as an union of multiple disjoint intervals by separating

them with a comma, an example: `\solution{(-infinity;2],[3;infinity)}`

Be aware that this is only possible if the optional command `\allowIntervalUnionsForInput`

is used.
