WHAT IS IT?
This model demonstrates the Place Value method of converting a floating point number from any base to decimal. You may choose any base in the range of two to sixteen, with a maximum of five digits to the right of the radix point.
HOW IT WORKS
The Place Value method first determines the powers by counting the digits starting with zero on the right. Next, the place value of each digit is determined. The place value is the base to the power determined in the first step. The third step is to multiply each digit by its place-value. The last step is to add all the products calculated in the third step. This gives us the decimal equivalent of an unsigned representation in another base.
HomeApplets 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.
