Fix precedence of interval operator

Browse Source 
The interval operator has a lower precedence than, for example, binary
operations. This was unexpected and incorrectly implemented in the
output functions. For now, this is fixed by enclosing intervals in
parentheses to avoid misinterpretations.

The existing unit tests are adjusted to the updated output format.
