 In the case where the number of digits that make up the outcome value exceeds the number of r-values that the oracle committed to, the oracle should sign the maximal possible value that it can attest to.
 In the case where the outcome value became negative but the oracle did not provide an extra R-value, it should sign the value 0.
 The minimum and maximum values that can be attested to by an oracle should thus be interpreted as `max_value or more` and `min_value or less`.

 The oracle must separately provide an array of R values, one for each of the digit that will be signed, with the first value of the array being used for signing the leftmost digit. If the is-signed value is true, an additional R-value must be provided as the first element in this array, which will be used to sign the string "+" in case of an outcome with a positive value or zero value and the string "-" in case of an outcome with a negative one.
 In practice this array is provided as part of the [Oracle events](#Oracle-events) structure.

+For example, one considered approach was to require the oracle to sign the number of digit that make up an outcome.
+Another one was to sign a flag indicating overflow.
+However, these make the specifications more complex, without providing any clear benefit (or without the currently specified approach having any clear downside).
