I am delusional about everything because I am amazing.

[animatronic-christmas-chickens]

Just for fun, some info about the symbol ÷. It is literally a dot in the numerator and a dot in the denominator, where the object to the left replaces the first dot and the object to the right replaces the second. As for the style guides, I would love to have references, because I strongly suspect "everything to the right" is for things like 3÷236 and not 3÷200+30+6.

However, and I'm opening a can of worms here, we could avoid the issue entirely by using either prefix notation: × ÷ 6 2 + 1 2, or (my preference) postfix notation: 6 2 ÷ 1 2 + ×. This notation is unambiguous. Using spaces as delimiters, there is only one way to interpret each of these expressions.

Note, prefix notation such as × ÷ 6 2 + 1 2 is closely related to function notation as in MUL(DIV(6,2),ADD(1,2)).

Postfix notation is also used in computer-related languages such as Adobe's PostScript plotter of language:

6 2 DIV 1 2 ADD MUL

which yields 9 as the result.

Postfix notation was also used by some of the earliest high performance scientific calculators, where it was referred to as RPN.

Calendar of Auldrant

Though I do not know if other games in the Tales series go by a similar date and day naming system, this will primarily be Tales of the Abyss. This is a long post!

Here is all the information the game gives regarding the calendar.

The Days:

This is a funny nod towards the origins behind the names of the days of the week. Rem is light and the “Sun” in Sunday is directly referencing the Sun. It's pretty neat that both reference a form of light. 

Similar situation with Lunaday and Monday (Luna- Moon, Mon- also Moon). 

Ifrit(also spelled Efreet) is Fire. Potentially in Korean the Tuesday equivalent translates to “fire day” according to Wiki about Tuesday. I don’t speak or read Korean so I also checked WordReference and found similar characters in some of the words like rage, wrath, ire, (further down that provided list) great fire. So it potentially could be a fun nod to that, can’t completely confirm. 

Undineday is water day. In Japanese and Korean Wednesday also translates to Water Day. Yes, in WordReference the Japanese character used in Wednesday is used for water so this seems fairly straightforward. In Korean I also found a bit more difficulty as the characters are widely used in many words, there are some water-related words in the sea of words the character appears in so I wouldn’t completely dismiss the possibility. 

Sylphday is wind. Thursday is a reference to Thor, the god of thunder. The wind would relate to stormy weather that thunder and lightning often appear with. 

Loreleiday- Lorelei. Friday- the greatest day of the week. In Auldrant Lorelei is considered pretty great! Just kidding, well partially. Friday comes from Freya, the goddess of marriage and love. Lorelei is a godly figure in the world of Abyss. Though Lorelei may be caring, it’s more related to sound and memory. Daath in general is fairly religious, following Lorelei, with the Order of Lorelei. In Christianity, Good Friday is a widely celebrated day. In Catholicism, all Fridays during Lent, you can’t eat meat (but it is supposed to be all Fridays to abstain from meat not just Lent). This being Friday's equivalent does make sense with the more religious aspect of the day (since Sunday was used for the more straightforward “light” connection).

The Gnomeday-Saturday connection is fairly nonexistent. Gnome is the element earth in Auldrant. Saturday is a reference to Saturn (God of Time), sabbath day (for romantic languages), and bath day (Old Norse). I will be honest, none of these fit. Sadly, it may be a case of “just put it in somewhere.”

The Months:

There are 13 months in Auldrant. As far as I can tell, there is no official count of how many days are in each month.

If we ignore Lorelei Decan for a moment, the rest of the months go forward and reverse except for Rem Decan and Luna Redecan (which is in place of the counterpart of a potential Rem Redecan). The order of Rem, Sylph Undine, Gnome, Ifrit, and Shadow are not in the order of fonon numbers. The number order of this month list is 6, 3, 4, 2, 5, 1, 1, 5, 2, 4, 3, 6, 7. I am assuming Luna and Rem are two sides of the same coin and are referencing the same fonon so they are both the 6th fonon. There was close to being a pattern of taking a number, halving it, adding one, and halving it again but they ran out of whole numbers to continue that.

The first half of the year has the postfix Decan and the latter half Redecan except for the Lorelei month. This could be because Lorelei signifies that a new year will arrive, so it has the postfix Decan. Lorelei is an important figure in Auldrant, especially Daath, so a month that stands out in the name of Lorelei would be fitting.

To think of a wild interpretation of the months, it could represent a person’s life or the year’s lifespan. The beginning starts with the sun, a new beginning. The person/year goes through the experiences of their life, experiencing all it has to bring (with fonons making up the world). The center point of the person/year’s life is the Shadow months. At this point, they are no longer young and will have to figure out what to do for the rest of their life (a very shadowy midlife crisis). They reminisce about their life and go back to relive the experiences of their youth until the sun sets and the moon rises. The end of the line. Then as all 7th Fonists do, they return to the Fonbelt, to Lorelei. Then the cycle of fonons can begin again. 

Or a more logical explanation of the months could represent the cycle the memory particles go through when traveling through the Fon Belt (The Planet Storm). Then to encompass all the Fonons Lorelei represents the final one of the 7th Fonon.

Anyway, all the months can comfortably fit 58 days in them but there is a remainder of 11 days to account for in the year. If we add a day for every other month starting with the first month, that would leave 4 days remaining. I do not know a logical placement for these days, so I will add them to Lorelei Decan. The month count would be Rem Decan- 59, Sylph Decan- 58, Undine Decan- 59, Gnome Decan- 58, Ifrit Decan- 59, Shadow Decan- 58, Shadow Redecan- 59, Ifrit Redecan- 58, Gnome Redecan- 59, Undine Redecan- 58, Sylph Redecan- 59, Luna Redecan- 58, Lorelei Decan- 63. (This will be helpful for some calculations later.)

The Year:

A year in Auldrant is 765 days. That is 2.1 times longer than our calendar year. If we compare that to our world, Jade would be 70, Guy 42, Natalia 36, Tear 32, and Anise 28. Dang does Jade look great at 70 haha! I do know the 765 days is a pun because that number sounds somewhat like Namco in Japanese. In this world, I assume people age at half the rate (My condolences to all the Auldrant parents with tantrum-throwing toddlers). Since the year is twice as long, Luke being locked in his Manor for seven years and the time skip in the story would be way longer than originally believed. Nothing like Auldrant continuing to be worse and worse, right?

Birthdays:

Can't have a ramble about a fictional calendar without talking about birthdays! From around the internet, the birthdays of the characters are listed as follows: Jade- Sylph-Redecan 22, Guy- Efreet-Decan 41, Natalia- Rem-decan 37, Luke- Lorelei-Decan 48, Tear- Lorelei-Decan 1, Anise- Shadow-Decan 46. Going along with my guess on how many days per month, the day each character is born in this: Jade- 607, Guy- 275, Natalia- 37, Luke- 750, Tear- 703, Anise- 339. (Basically, add up all the days of the months prior and add then the day of the month they were born). The birthdays I got from fan sites that supposedly got them from a QNA. I do not know the accuracy of these but for the purposes of the rest of this, these are the dates used.

I have noticed that there are assigned birthdays for the characters per our calendar year. Jade is Nov 22, and Luke is Dec 25th. I found these from fan sites and repeated them across the internet. Again with these, I do not know the accuracy, so I did my own take on the potential calculations.

There are a few ways to calculate the birthdays of these characters with our own: Divide the year by two (2.1 to be more accurate) and get an approximate answer, place our calendar year onto Abyss’, and count the days (for example there will be two Decembers).

The first option is easy. Divide the day they were born by 2.1 to get the day they would be born on Earth. It would land the characters birthdays like this: Jade- 289 (Oct 16), Guy- 130 (May 10), Natalia- 17 (Jan 17), Luke- 357 (Dec 23), Tear-  334 (Nov 30th), Anise- 161 (Jun 10). These are pretty close to the associated birthdays with Luke nearly being a Christmas Eve baby and Jade being born in fall.

The second option is also easy, for any character whose birthday is over 365, subtract 365 until it is a number below 365 and find the date associated (For example, if a character is born on the 366th day, they would be born on Jan 1st in our calendar). It would land the characters birthdays like this: Jade- 242 (Aug 30th), Guy- 275 (Oct 2nd), Natalia- 37 (Feb 6th), Luke- 20 (Jan 20), Tear- 338 (December 4th), and Anise- 339 (December 5th).

Despite the numbers not exactly lining up (there will be human error on my part with calculations and rounding), if people celebrate Jade's birthday on Nov 22 that's completely fine by me! It's a fictional birthday anyway! If it means more Tales of the Abyss art and content, Jade's birthday could be Feb 14 for all I care!

This was just something fun I've been thinking about when I learned about the calendar of Auldrant! And might as well try to put all my thoughts together for a big ramble. Hope you all enjoyed!

There is no interpretation of the problem-as-stated-by-op where "add 1" is the complete solution.

OP says to do this operation on "an integer"

It cannot mean "the platonic model of an integer" because those have no bits and also cannot be represented in digital logic e.g. the integer might be Graham's Number.

It also cannot mean "keyword integer" because C doesn't have that keyword.

it could mean "keyword int." Probably not - OP uses "uint32_t" but it could. In that case, adding 1 to 0xFFFFFFFF is undefined behavior.

it could mean "machine word integer" which is more probable given the use of "uint32_t" as the input. The machine word integer does not have a carry bit.

BUT

PLAYING with the IDEA that you should always increment by 1, the correct implementation does not use c++, it uses ++c:

a = c++; -> No. a does not contain the value as specified.

a = func(c) where func(c){return c++;} -> No. a does not etc./

a = ++c; -> No. a correct, but c modified and spec "a function" not implemented.

a = func(c) where func(c){return ++c;} -> No. Correct implementation of functional requirement, weird implementation of default nonfunctional requirement "perf" (assembly different from "return c+1")

a = func(c) where func(c){return c+1;} -> Correct.

Godbolt

"But that's in debug mode turn on the optimizer" what you think you can get away with writing bad code just because your clients can optimize? What if they're running in debug mode to find your weird off-by-one mistake?

An additional thoughts about Shi Qingxuan's ascension (additional to this).

God of what he was? Of wind. And...? I mean, Shi Wudu was god of water AND trade. Yushi Huang is the god of rain AND harvest. Ming Yi is the god of earth AND builders.

And Shi Qingxuan was god of wing AND ...?

That's why when he refused his god's powers they just gone. Because his powers were connected just to the element, but not to some sphere of real life. His ascension was artificial, he was constantly given powers by Shi Wudu and a lot of artifacts, that masked simple thing - he doesn't know what to do with his godhood except constantly trying to impress older brother.

He calls "Ming Yi" "Ming-xiong". But "-xiong" is a postfix that Chinese use to address elder friend, it's sign of respect. But in fact, Ming Yi (not He Xuan, but Ming Yi) is younger then Shi Qingxuan, weaker and not so reach. Why Shi Qingxuan treat hin as older, more experienced one? Because he needs some big brother in his life. He tries become more then a shadow of Shi Wudu, but can't separate and just finds a brother figure, some -xiong, who he treats like older brother and sees them as inseparable pair.

(Poor Shi Qingxuan, all this friendship was so lie, I doubt he calls someone -xiong again in his life)

Shi Qingxuan could be a god. He could ascend. He just need to grow up and understand what he wants, what he wants to do as a god for people, not for his brother, not for his friend. Instinctively, he feels thet he must become the defender of poor, homeless, unlucky. Maybe this is the voice of He Xuan's fate, this is what He Xuan destined to be, but never become.

Will Shi Qingxuan find his path? Moxiang Toungxiu don't answer "yes" or "no". But she shows that he could survive, have enough inner strength to save kind heart even after treachery of people he loved most, and to walk the hard path of learning what re really want and can do.

So, let's prey that Moxiang Toungxui write an extra about Lao Feng, gof of Wing, wanderers, poor and homeless, and maybe healing. God with not fan, but cane.

[ … can we have standardized tagging for the apparently plot relevant transphobia and other things or something. ]

[ this sorta issue went around a years ago in other rp communities- adding tw or cw or // to the beginning or end of a warning tag makes it much more difficult to catch in blacklists, due to the sheer variety of prefixes AND postfixes. you don’t need to add a pre or postfix. just the “ic subject” is fine ]

[ i am proposing this because many people do want to stay up to date on current events, such as the horrors, but at least want a Heads Up if they transphobia, abuse, homophobia, or racism(last one hasn’t been spotted in this community yet)(not a challenge) is going on in character ]
