I was trying to find the 1,852,083rd prime number and the 1,852,083rd Fibonacci number to full precision. I found the prime number (29,901,239). Since it is only eight digits long, this was not that big of a deal. I am still trying to figure out all of the digits of the Fibonacci number though. Perhaps someone can help me with this.

I think that I recognize the name Mupad. It seems familiar. I am not exactly sure where from, but it seems somehow familiar. Strange

That should help add to the collection.

What were those programs. I am going to guess that, based on the fact that there is a topic entitled Coder's Corner, that you programed ≥ 1 of those programs.

## #5 Re: Help Me ! » Calculating an Excel Column » 2010-12-28 05:23:06

I will have to think here. Two specialized math programs to do the calculationshmmm:
1. Wolfram
2. Unsure, but perhaps something like another supercalculator

So, you want some code, eh? Here is some code for you. Hopefully this logic will help you understand that fiction (and fake things) (I will describe that second.) are indeed real.

1 using nonexistent as the opposite of real;
2 Item_X = anything;
3 if(Item_X exists in the world of nonfiction && Item_X does not exist in the world of fiction)
4 Item_X is real.;
5 elseif(Item_X exists in the world of fiction && Item_X does not exist in the world of nonfiction)
6 Item_X is real.; //I think that this can be considered "Confusion: Part 1 of 2" for most people.
7 elseif(Item_X exists in the world of fiction && Item_X exists in the world of nonfiction)
8 Item_X is real.; //I think that this can be considered "Confusion: Part 2 of 2" for most people.
9 else
10 Item_X does not exist in either world and thus is not real.;

Now for the term fake:
I think of this as a synonym for false. A common example is fake fruit. Using the logic above, it is real due to its existence. It is fake, however, because it supplies no sustenance (because it is generally made of plastic, which does not supply sustenance that I am aware of).

I am not sure if I would classify Peach as a snob even though she does get kidnapped often. Oddly enough, it seems that most people prefer Peach over Daisy. Some people seem to believe that she "needs to get a life." Based on what I see of her and her possessions, I am not sure that it would be surprising if some see her as an idol worthy of worship (though she is not worthy of this at all) (There is only One who is truly worthy of all worship and praise.) (and no, that is not warship, that is wership) (I think that Daisy's ship is a cruise ship anyway.) She seems to have a life to me. It seems to be a life of mostly happiness, but Bowser and his children certainly do not help this last. I am not fond of their personalities at all. Even Wario's and Waluigi's personalities (which I am not totally fond of as well) are not nearly as brutal as those of Bowser and his children. I will say though that Bowser mistreating his own son is kind of interesting. I suppose that definitely shows favoritismtoward brutalityhmmm (although Wario and Waluigi are thieves, this is not good either).

To give you an idea of my appreciation for Daisy:
1. I made a button (which I am not exactly sure where went) in photography class. Daisy's head is on a tree branch in the background.
2. I also made a calendar in photography class. On February (which, looking back, I find quite interesting due to the fact that Valentine's Day just happens to be February 14th), there is a picture of Daisy.
3. My profile picture for Windows is a picture of Daisy.
4. I am a member of a forum dedicated to Daisy.
5. I am [still] trying to figure out a way to make a song with a pattern quantity ≥ Daisy (1,852,083). I have tried a few combinations, but they did not work due to the program that I use (which can be read about by clicking or tapping the link in this list item) running out of memory.
6. My father and I have a couple of devices that have Android OS installed on them. There is an application for it called Daisy Garden. With this application, the user plants virtual flowers in a garden and can do just about anything with them. They can be moved, named, tagged as favorites, uprooted, or viewed on the devices homescreen. Flowers are widges, so you can plant them at any time. This is how they are transferred to a garden (There is a total of nine different types of garden.) Anyway, on to what I wanted to say. On one of the devices, I took about a couple of weeks (perhaps) to plant flowers and form the phrase Caleb's, Daisy's, and Jerry's gardens (all in uppercase letters though). On the same device, I have set up seven home screens with the first five containing flowers in the forms of D, A, I, S, and Y. The last two home screens have exclamation marks on them. On the other device, my father made the word Daisy on one of the home screens. Prior to this, he and I had started making the word Daisy in such a fashion that there was a large letter with a smaller version of the same letter within it. It had a heart on the sixth home screen.
7. The desktop background for both my tablet PC with Windows on it and my desktop is a siimple video with a field of daisies blowing in the wind.
8. I have an inspirational calendar (that I believe is now out of print unfortunately) entitled Daysies. Some days have inspirational thoughts on them. Some have inspirational quotes on them. Some have inspirational Scripture verses on them. It is a nice calendar indeed.
This gives you an idea of my appreciation for Daisy. And that is not the end. If you would to read more, I can post it.
Although, if you read stories like this one, you might not necessarily get that impression.

Lowercase and uppercase is irrellivant. How did you do these? Based on how quickly the response seems to have come, I am guessing that you did not use Excel to find the number for Fluffy Puff Marshmallows and the phrse for 16,777,216 because if you did, then it probably did not come as quickly as I as thinking. As far as I know, Excel does not allow inserting the alphabet and dragging it to test these (though perhaps it does and I am just unaware of it). Based on your description of the math tag, it essentially changes the font face to look more like is often seen for mathematical expressionslike the bold or italic tag.

I like the first post in this topic. If I am reading it correctly, perhaps the person that posted it does not like profanity. Psst, I don't like it either. Oddly enough though, there is an emoticon labeled . I assume that this means something profane (as opposed to making a promise or swearing an oath) based on the fact that the face is red and it would appear that the fist is being pounded.

Have you ever wondered what lies behind that mysterious labeling system that Microsoft uses for Excel? It is a system of alphabetical strings that can be converted to numbers using the following polynomial function:
(26[sup]string length - 1[/sup] * letter position) + (26[sup]string length - 2[/sup] * letter position) + (26[sup]string lengh - 3[/sup] * letter position) +  + (26[sup]string length - n[/sup] * letter position)
The function in action:
(26[sup]4[/sup] * 4) + (26[sup]3[/sup] * 1) + (26[sup]2[/sup] * 9) + (26[sup]1[/sup] * 19) + (26[sup]0[/sup] * 25)
As you could probably guess based on the formula and the numbers used that this decodes the word daisy (1,852,083). I have also decoded much more complex things as well such as weird (10,604,884) and Fluffy Puff Marshmallows. I do not recall the number for Fluffy Puff Marshmallows though. What I would like to do though is do this formula in reverse. I would like to figure out the equivalent string for the number 16,777,216. Does someone know how I can accomplish this? By the way, what does the math tag do? I am not familiar with it.
