What's New - December, 2006
December 17, 2006: We are off to Connecticut in the morning to visit the daughter and grandkids that couldn't make it here for Thanksgiving. So don't be alarmed if emails do not get answered for awhile. We'll be enjoying the holidays but I'll see you you again next year. In the meantime,
Have a safe and happy Holiday season!
December 7, 2006: There are a number of word related programs here on DFF that use a compressed dictionary format for fast word retrieval. A program Dicmaint is provided to maintain the dictionary. . A small fix to Dicmaint (included on the Wordstuff2 program page) was made today. For programmers it is significant that an older version of the dictionary unit was being distributed with the Wordstuff and Dicmaint source code. As of today, the version contained in the DFF library unit will be the only one distributed. See the above link for more information;
December 6, 2006: Charles Doumar has done much of the follow-on development in our unit for very large floating point number arithmetic, UBigFloatV2. His latest additions were posted today in a new version of the DFF library zip file, DFFLibV08. The BigFloat Test program was also reposted with tests for some of the new methods, specifically for calculating natural and base 10 logarithms, a Power function (xy) and Exp, to calculate ex for very large numbers.
The library file contains a number of units in addition to UBigFloatV2. Its purpose is to provide a common location for units which are used in multiple programs posted on this site. This centralized location concept simplifies maintenance when changes are made to library units. A number of units in DFFLibV08 have had minor updates:
December 2, 2006: A new word puzzle is
available today. Word Squares
is based on puzzles found several times a year in our Mensa Page-A-Day Puzzle Calendar.
Player must complete a square grid of words, each word running both
vertically and horizontally and using all of a given set of letters. A
example is shown at right: The starter word is "FIND" and three
additional 4-letter words must be formed beginning with the letters I,
N, and :D and containing the 9 letters: "AADEEETTX". The program
will generate random puzzles, allow you to solve them or show show you the
solutions when you get stuck. Grids may be 4x4 or 5x5. The 5X5
grid increases the chance that you will be using that "I give up" button!
