All the keyboards in the world were similar. Even the special keyboards in the library were similar to the keyboard of this laptop. Pi stared at the keyboard for a while, and quickly pressed the first key.
Zhang Zian peeped through the crack in the door. From his position, he couldn't see which key Pi pressed, but it should be the number area of the keyboard, which was the row above the 26 English letters. After all, this laptop didn't have a special keypad area.
So, Zhang Zian couldn't see it, but he could guess what Pi was typing. It must be Pi again.
Why was Pi using Pi as Pi? Was it to relax? Just like how humans could relax by playing games?
If he remembered correctly, the default search engine on the homepage of the browser limited the length of the data in the search bar, so it couldn't type infinitely.
Sure enough, Pi opened its mouth in shock, staring at the screen. It repeatedly pressed a number on the keyboard with its finger in vain, but it couldn't type the number.
"Eeek!"
After failing several times, Pi held its head with its hands, as if it was very anxious. Its fingers pulled the short hair on its head, like a high school student who was troubled by a difficult math problem.
Zhang Zian thought about it, tiptoed downstairs, and then walked up the stairs at a normal pace so that Pi could hear his footsteps and wouldn't be scared.
He pushed open the door of the living room, stretched, and walked in, pretending to know nothing. He said to himself, "It's not easy to finish the work. It's so tiring..."
Pi had left the computer and sat on the sofa, pretending to be reading. Unfortunately, it forgot to close the browser before it left.
Zhang Zian sat back in front of the computer, pretending to be surprised. "Hey, I remember I closed the browser before I left..."
As expected, the search bar of the search engine was the long string of Pi numbers.
"Eeek!"
Pi lowered its head and covered its face with its hands, like a child who had done something wrong, waiting for Zhang Zian to scold it.
"Is it the browser that Pi opened? So smart! Other elfins don't have this ability. Only Pi knows how to use a computer, "Zhang Zian praised it unexpectedly.
"Eeek?"
Pi put down its hand and stared at him.
"I'm serious. Look at that African grey parrot that claims to be proficient in all languages. It doesn't even know how to use a mouse, let alone accurately type the first 100 digits of pi." He spoke ill of Richard behind his back.
In fact, he wasn't sure if the first 100 digits of pi that Pi had typed out were correct, but it didn't matter, as long as it could increase its confidence.
"Jiji!"
Pi beamed with joy, holding the book in one hand and patting its chest with the other.
Zhang Zian carefully tried to figure out what it meant, and asked tentatively, "Pi is saying that you can play more than just the top 100?"
"Jiji!"
Pi nodded vigorously.
"Uh … How many digits can Pi hit?" he asked curiously. "200 digits?"
Pi shook its head and stretched out its arms.
Does that mean … it's bigger than 200?
"That's 500?"
"Jiji!"
Pi was still shaking its head proudly. Its arms were stretching outwards as if it was doing radio gymnastics.
"Uh …" Zhang Zian tried to guess again. "1000?"
"Jiji!"
Pi's movements were even more exaggerated. Obviously, it wanted him to guess a bigger number.
Zhang Zian sweated because he couldn't believe it. He didn't know what the longest number of digits of pi that a human could recite was. He couldn't imagine how this infinite number could be recited, so he guessed again, "10,000?"
"Jiji! Hehe! "
Pi looked a little anxious, and its movements were even faster. It seemed that Zhang Zian's guess was too small.
"Okay …" Zhang Zian felt that it would be a waste of time if he didn't add ten times more. Since Pi was so confident, he would say a big number.
"10 million?"
He said the number nervously, afraid that he would guess too big and hurt Pi's self-esteem. This number was impossible for a human to recite, because it was beyond the physiological limit of a human.
Assuming that he could recite ten numbers in one second, and recite for eight hours a day, it would take him a month to recite all 10 million digits.
"Jiji!"
Pi still shook its head, jumping and raising its arms, asking him to continue guessing.
Zhang Zian was speechless.
Even if he trusted Pi, he couldn't help but wonder if it liked to brag like him.
Since his laptop was on, he checked on the search engine. So far, the value of Pi had been calculated to 60 trillion digits after the decimal point. No matter how powerful Pi was, it was impossible for it to memorize 60 trillion digits, right?
"Jiji!"
Pi saw that he was doubtful, so it anxiously patted its chest and waved the nameless book in its hand.
"You mean, you can't do it by yourself, but with this book, you can do it?"
Zhang Zian could more or less understand Pi's expressions and movements. After all, Pi was a young monkey, so it was as naive and easy to understand as a human child.
Pi nodded.
"Okay, then I'll guess a little bigger." Zhang Zian chose to believe it for the time being. After all, Pi was the only elfin with a golden finger so far, and the golden finger was, of course, the scarlet nameless book.
Pi nodded expectantly.
"1000 trillion digits?"
This was his last guess. Even if he still didn't get it right, he didn't plan to guess anymore, because he didn't know what the larger unit was. If he guessed again, he would only make a fool of himself.
For a moment, Pi's expression didn't change. Just when Zhang Zian thought he guessed correctly, it grinned and continued to shake its head.
Zhang Zian raised his hands. "I surrender. I really can't guess it. Just tell me directly. "
"Jiji!"
Pi scratched its ears and cheeks, as if it couldn't express its inner thoughts. Finally, it clenched its empty hand into a fist and loosened it a little, as if it was holding something tightly and then slowly letting go.
What did that mean?
Zhang Zian was confused. After all, he wasn't a sign language expert, and Pi's gestures weren't standard sign language.
"Jiji!"
Pi jumped off the sofa, holding the nameless book in one hand and the other hand on the floor as it ran to the storage room. After a while, it hobbled on two feet like a human and came back with a bag of cat litter.
Zhang Zian didn't know what it was going to do, so he watched it quietly.
Pi tore open the bag of cat litter and poured some on the table. Then it grabbed a handful of cat litter and let it slide from its palm, showing it to Zhang Zian.
Zhang Zian was even more confused. He was asking how many digits Pi could write. What was it doing with cat litter?
Pi saw that Zhang Zian didn't understand, so it grabbed another handful of cat litter and let it slowly slide from its palm.
Zhang Zian seemed to have seen similar actions in movies and animations. It was like someone grabbing a handful of yellow sand and letting it slide from his fingers, then being blown away by the strong wind.
Wait a minute!
Zhang Zian suddenly had an idea. A bolt of lightning exploded in his mind, illuminating the darkness! He remembered that one of the units seemed to be related to "sand"! But that unit was so large that it made people feel hopeless …
"Is it as small as the number of grains of sand in the Ganges River?"
When he said this, even he couldn't help but tremble. He even had goosebumps all over his body.
The number of grains of sand in the Ganges River was a term from the Buddhist scriptures. It was a double metaphor. Assuming that every grain of sand on both sides of the Ganges River represented a Ganges River, the product of the grains of sand in the Ganges River and the grains of sand in the Ganges River was the number of grains of sand in the Ganges River. It was difficult to express exactly how large the number was. It was generally regarded as immeasurable.
"Jiji!"
Pi finally nodded. It was so excited that it danced with the nameless book, as if it was very happy that Zhang Zian had guessed correctly. This also meant that it could write pi to infinity, even to the end of time, longer than the lifespan of the universe. Pi could write pi as long as the infinitely non-cyclic decimal number was!
Zhang Zian didn't know what to feel. On the one hand, he was deeply shocked. On the other hand, the number was so exaggerated that it couldn't dispel his doubts. Did Pi really know how astronomical the number of grains of sand in the Ganges River was?
The biggest question was … What was the use of this?
Generally speaking, in the common calculations in high school and college, one only needed to write Pi as 3.14. Even if it involved some industrial calculations, one only needed to take the first ten digits of Pi. More accurate calculations in the scientific field only used a few hundred digits of Pi. What was the use of being infinitely accurate?
If a human could recite Pi to tens of thousands of digits, he could apply for the Guinness World Record. He could become famous, he could become an Internet celebrity, he could flirt with girls at parties, and he could even write a book that taught you how to improve your memory to make money. But what was the point of this to elfins? It couldn't be to show off in front of other elfins, could it?
Both humans and elfins needed meaning and purpose to do things, and they also needed to pay attention to the cost-performance ratio. Obviously, reciting Pi to infinity was the lowest cost-performance ratio way to show off, because no one knew if what you recited was correct.
Pi didn't think so. It was deeply proud of itself. Holding the nameless book in its hand, it squeaked and happily walked in circles in the living room.
Zhang Zian's eyes fell on the book. The answer must be in the book. Even Pi itself admitted that without the book, it couldn't recite Pi to infinity.
This was a book about life, the universe, and everything. If this was true, it must include Pi.
It was useless to keep guessing. When Pi trusted him enough, he would definitely ask Pi to take a look at the contents of the book. It would be best if the book wrote when he could find a girlfriend …
He looked at the time. It was time to make tea for Old Time Tea.
"Pi, wait for me. I'll be back soon." He walked into the kitchen, filled a pot of cold water from the tap, and put it on the gas stove.
He just wanted to drink this bowl of Ganges River water to calm down.
