**Section: Rules for real number questions**

We test the answer to a real number question using the phrase 'the number understood'.

There are two default rules for processing answers to real number questions.

The first rule, called 'the invalid real number reply rule', operates where the player enters an answer to a real number question that is not a real number. If the question is a closed number question, the outcome is retry. If the question is an open question, the outcome is parse.

The last rule, called 'the default real number question rule', has the outcome exit.
