HOW TO USE IT

If you want examples from a specific base: Use the number-of-digits slider to set the number of digits for the decimal number. Use the base slider to set the base. Now press the setup button. This will generate a random number with that many decimal digits. If you are converting to base 2, you will not be allowed to have five decimal digits because then the result has too many bits.

If you do not care which base is used, click the random button to generate an arbitrary base, number-of-digits, and number.

The slow-motion slider is an easy way to adjust the speed of the display. Set it to zero if you want to show the final result as quickly as possible. 0.25 is a good setting for most purposes.

The step button does a single division, and copies the remainder to the display at the bottom. It then stops so you can take notes. This is useful when you are first learning the method.

The go button continues dividing until the quotient is zero, at a speed determined by the slow-motion slider. This is useful when you do not need to take notes between each step.

The show-again button starts the exact problem from the beginning. You may then click either the step button or the go button to see the same demonstration.

The quiz button will generate a random number using the number-of-digits slider, and ask you to convert it to the base on the base slider. If you want to drill conversion to hexadecimal, set the base to 16 and the number-of-digits to a small number.

Applets on this website were written by Teresa Carrigan in 2004, for use in computer science courses at Blackburn College, with the exception of the Fireworks applet. The applets made with NetLogo require Java 1.4.1 or higher to run. The applets made with NetBeans require Java 1.4.2 or higher to run. Applets might not run on Windows 95 or Mac OS 8 or 9. You may obtain the latest Java plugin from Sun's Java site.
