The keyboards all over the world are similar. Even the dedicated keyboards in the library are almost the same as those of this laptop in terms of layout. π stared at the keyboard for a while, and soon pressed the first key.

Zhang Zi'an peeked in the crack of the door. Although he couldn't see which key was pressed from his position, the general position should be the number area of ​​the keyboard, that is, the row above the 26 English letters. After all, this laptop does not have a special keyboard area.

Therefore, Zhang Zian couldn't see it, but he could guess what π was hitting, and it must be pi.

Why does π need to play pi? Is it for relaxation? Just like humans can relax when playing games?

If he remembers correctly, the default search engine of the browser homepage limits the data length of the search bar and cannot be infinitely played.

Sure enough, π quickly opened her mouth in surprise, stared at the screen, and repeatedly pressed a number on the keyboard with her fingers, but she could not type the number up.

"Squeak!"

After several failures, it hugged its head with its hands as if it was very anxious, and its fingers pulled the short fluff on its head, like a high school student troubled by profound math problems.

Zhang Zian thought about it, tiptoed down the stairs gently, and then went upstairs at normal or even heavy steps, so that π could hear his footsteps and not be scared.

He pushed open the living room door, pretended not to know anything, and walked in with his waist stretched, saying to himself: "It's so tiring to finish the work after finally finishing it..."

π has left the computer, sat on the sofa next to him, and pretended to be reading a book, but unfortunately it forgot to turn off the browser before leaving.

Zhang Zi'an sat back in front of the computer and stared at the screen in surprise, "Hey, I remember I had turned off the browser before leaving..."

As expected, the search engine's search bar is exactly the long list of pi numbers.

"Squeak!"

π is like a child who did something wrong, lowering his head and covering his face with his hands, waiting for Zhang Zi'an to scold him.

"Is it a browser that opens with π? π is so smart! Other elves don't have this ability, only π can use computers." Zhang Zian praised unexpectedly.

"Squeak?"

π put down her hand and stared at him blankly.

"I mean, look at the African gray parrot, which is known as proficient in all languages, doesn't even use a mouse, let alone accurately hit the top 100 pi." He said bad things about Richard behind his back.

In fact, he didn't know whether the top 100 pi digits produced by π are correct, but it doesn't matter, as long as it can enhance its confidence.

"Squeak!"

π smiled happily, holding the book with one hand and patting the chest with the other.

Zhang Zi'an carefully understood its meaning and asked tentatively: "π means that you can not only score the top 100?"

"Squeak!"

π nodded vigorously.

"Uh...what can π play?" he asked curiously, "200?"

π shakes her head and stretches her arms straight.

This means... bigger than 200?

“That’s 500?”

"Squeak!"

π still shook her head proudly, and her arms were stretching out as if they were doing a radio gymnastics stretching movement.

"Uh..." Zhang Zian tried to guess again, "1,000?"

"Squeak!"

π's movements were even more exaggerated, obviously asking him to guess at larger numbers.

Because he was unbelievable, Zhang Zi'an was a little sweaty. He didn't know how many pi digits the longest pi could be recited by humans. He couldn't imagine how he memorized this infinite non-cyclic number, so he guessed again: "10,000 digits?"

"Squeak! Hoho!"

π's expression was a little anxious and his movements were even more rapid, as if he thought he was too small.

"Okay..." Zhang Zian felt that he would no longer add ten times or ten times. This was a waste of time. Since π was so confident, then he would just say a big number.

“10 million?”

He spat out this number nervously, for fear that he would guess too much and would hurt π's self-esteem. This number could not be memorized by humans no matter what, because it has exceeded the physiological limits of human beings.

Suppose you recite ten numbers in one second and recite for 8 hours a day, it will take one month to finish the 10 million digits.

"Squeak!"

π still shook her head, jumped up her arms, and asked him to continue guessing.

Zhang Zi'an: "..."

Even if he believed in π very much, he couldn't help but wonder if it likes bragging like himself.

The laptop just happened to be on, and he checked it on the search engine. So far, the pi value has been calculated to 60 trillion digits after the decimal point. Even if the π dick is so amazing, it is impossible for him to memorize these 60 trillion digits, right?

"Squeak!"

Seeing him showing suspicion, π patted his chest anxiously, and waved the nameless book in his hand.

"That means, you can't do it alone, but with this book, you can do it?"

Zhang Zian already understood the expressions and movements of π, and could guess the same thing. After all, π is a young monkey, as naive and easy to understand as human children.

π nodded.

"Okay, then I'll guess bigger." Zhang Zi'an chose to believe it for now. After all, π is the only elf with a golden finger that has appeared so far. The golden finger is of course the scarlet nameless book.

π nodded in anticipation.

"1000 trillion?"

This was his last guess. Even if he still didn't guess correctly, he was not going to guess further because he didn't know what the larger counting unit was, so he could only show his fear if he guessed again.

For a moment, π's expression did not change. Just when Zhang Zian thought he had guessed correctly, it grinned and continued to shake his head.

Zhang Zian raised his hands and said, "I surrender, I can't guess. π, just tell me directly."

"Squeak!"

π grind her ears and cheeks, as if she could not express her inner thoughts. Finally, it clenched the empty hand into a fist, then loosened it a little, as if she grabbed something tightly and slowly let go.

What does this mean?

Zhang Zian looked confused. After all, he is not a sign language expert, and the one who uses π to gesture is not a standard sign language.

"Squeak!"

π jumped off the sofa, holding the nameless book in one hand and running towards the storage room with the other hand on the floor. After a while, it staggered on its feet like a human, returning with a bag of cat litter.

Zhang Zian didn't know what it was going to do, so he watched quietly.

π tore the bag of cat litter open, poured some on the table, then grabbed a handful of cat litter, let them slide down from their palms, and signaled to Zhang Zi'an to show it.

Zhang Zian became increasingly puzzled. He was asking how many pi could be written out, and what did it do with cat litter?

Seeing that Zhang Zian didn't understand, π grabbed another handful of cat litter and continued to let them slowly slide from their palms.

Zhang Zian seems to have seen similar actions in movies and animations, just like someone grabs a handful of yellow sand and lets them slide from their fingers, blowing and scattering around by the strong wind.

Wait a moment!

Zhang Zi'an suddenly had an idea, and a lightning flash burst into his mind, illuminating the darkness! He remembered that there seemed to be one of the counting units that was related to "sand"! But that unit was so big that it was desperate...

"Is it as vast as the sand of the Ganges?"

When he said this, even he couldn't help but tremble, and even felt goosebumps all over his body.

The number of sands in the Ganges River comes from the Buddhist scriptures, which is a double metaphor. Assume that every grain of sand on both sides of the Ganges River represents a Ganges River, and the product of sands in the Ganges River and the sands of the Ganges River is the number of sands in the Ganges River. It is difficult to express exactly how big this number is, and it is basically considered immeasurable.

"Squeak!"

π finally nodded. It was so excited that it was holding the nameless book and dancing, as if very happy that Zhang Zi'an guessed it correctly. This also means that it can write pi to infinite length, or even to the end of time, which is even longer than the lifespan of the universe. The infinite non-cyclic decimal is, the longer it can write pi!

Zhang Zi'an didn't know what it felt like. On the one hand, he was deeply shocked, and on the other hand, the number was too exaggerated to dispel his doubts. Do you really know how big the astronomical number of the Ganges sands is?

The biggest question is...what is this useful?

Generally speaking, in common calculations in high school and college, you only need to record the pi as 14. Even if you involve some industrial fields, you can just take the top 10 digits of pi. More accurate calculations in scientific fields are just a few hundred digits of pi. What's the use of infinitely accurate?

If humans recite pi to tens of thousands of digits, they can apply for the Guinness World Record, become famous, become internet celebrities, and play girls at parties. Maybe they can also publish a book that teaches you how to improve your memory to make money, but what does this mean to elves? It can't be to show off in front of other elves, right?

Whether it is a human or an elf, doing things requires meaning and purpose, and it also requires cost-effectiveness. Obviously, memorizing pi to infinity is the lowest cost-effective way to show off, because no one knows whether what you memorize is correct.

π didn't think so. It was deeply proud, holding the nameless book in its hand, squeaking, and happily circled around the living room.

Zhang Zi'an's eyes fell on that book, and the answer was definitely in the book, and even π himself admitted that without that book, it would not be able to recite pi to infinite size.

This is a book about life, the universe and everything. If this is true, it must include Pi.

It would be useless to guess any more. When π trusts him enough, he will definitely ask π to show him the content of the book. It is best to write about when he can find a girlfriend...

He looked at the time and it was time to make tea for the old tea.

"π, wait for me a while, I'll go back." He said, then walked straight into the kitchen, picked up a pot of cold water from the faucet, and put it on the gas stove.

Now he just wants to do this bowl of Ganges water and calm down.
Chapter completed!
