Recursion is the topic of today's quiz. Put on your thinking cap and make sure there is a backup thinking cap under that and another one under that and another one...

After the quiz, we will continue thinking about how we as humans can convert numbers from one base to another and then how to get a computer to do it. If you think you know, try out your answer on the sumDigits. Try to answer both recursively and iteratively.

We have already covered the sections of our textbooks dealing with binary and hexadecimal numbering systems, so this week's readings come from the internet. Here is an informal collection of links related to numbering systems:

• • Computer Numbering Formats

  • Binary numeral system

  • Ternary numeral system

  • Radix

  • Golden ratio base

  • Two's complement

  • Arithmetic overflow
