LOGBASEN is short for "Log with base N". Very simple to use. Just move the program to your calc, or plug in the program by hand if you don't have a link cable. I try to understand that some people don't have a cable, myself included. Once the program is on your calculator, run it, and input the base, and then the number. Once you have done this, it not only displays the rounded value, but it also stores the exact answer to variable C. I hope that it is helpful for you.
