THINGS TO NOTICE

Besides the special bit patterns that represent positive and negative infinity, what is the largest number that this format can store? The most negative? The smallest positive number?

When the bit pattern is one of the special ones, we do not have to convert the exponent to decimal.

THINGS TO TRY

Set slow-motion to 0.2, click setup, and then click go.

Set the special-bit-patterns switch to the type of problem you want to drill, then click setup. Attempt one step at a time on paper, and then click the step button to check that you did that step correctly.

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.
