Convert the octal number 314159 to decimal.

Solution. That is not an octal number! You can do the computation, even with Converter, to get the result 104561, but 9 is just not a legal octal digit. The version of Converter on the booksite includes such legality checks. It is not unusual for a teacher to try this trick on a test, so beware!
