Bright Sword Military System

Chapter 1267 Floating Point Arithmetic
Wang Xuexin first asked the hardware team to cooperate with Qiong Yigan to develop a relay computer.

What Wang Xuexin said to Joan was: "Joan, I sent some newcomers to learn 'Christopher' from you, I hope you can teach them more!"

Joan understood that.

The relay computers of the Eighth Route Army are ahead of the never-setting sun, and they exchange technology for parts, that is to say, it is enough to give the technology, and there is no obligation to send top scientists to cooperate with the never-setting sun.

On the other hand, although the Eighth Route Army has the technology of relay computers, they lack the practical foundation of mechanical computers. It seems reasonable to send new people to participate in this project.

"Don't worry!" Joan glanced at Hardware and the others, and replied, "I think we'll have a great time working together!"

Wang Xuexin was actually not worried that Joan would suspect anything.

On the one hand, things like "Christopher" and even relay computers are not complicated. If mathematicians know binary operations, they will know what they are doing, and hardware and other people have a good grasp of their physical structure... Physically, if If there is any difficulty, it is that the hardware and the like do not understand the complicated wiring of each unit.

But for these wiring rules, if mathematicians understand the essence of binary carry rules, it will not be difficult.

The other is that Wang Xuexin trained two mathematicians for several hours.

The training content is mainly binary.

Binary operations are commonplace in modern times, but anyone who has gone to college or studied computer basics knows this stuff.

But in this period when computers were not yet popular, especially in China, many people, including mathematicians, had never heard of binary...even though the invention of binary has a history of hundreds of years.

This is due to the fact that binary is of little use in life and practice.

If the modern era is not for the large-scale use of computers, I am afraid that binary will still not have a bright future.

Therefore, when Wang Xuexin talked about binary with two mathematicians, they all looked at Wang Xuexin suspiciously and said, "Head, although this is not difficult, does it have anything to do with the project we want to study?"

Binary is really not that hard, especially for these mathematicians.

The difficulty lies in combining these things with reality and inventing computers so that machines can do such calculations.

These Wang Xuexin can't tell them, because this is a matter of practice.

Wang Xuexin only told them: "When the time comes, you will know what it is useful for!"

It is said that when the two saw a machine like "Christopher" that used binary calculations and could even be decoded, they were so shocked that they didn't speak for a long time. They couldn't believe that there was such a machine in the world.

Seeing them, Joan just said to them: "Your regiment leader, comrade, has done a good job of keeping secrets!"

"What do you mean?" The two mathematicians were puzzled.

"It's no secret to you Eighth Route Army!" Joan replied, "And you have more advanced ones!"

This once again shocked the two mathematicians beyond belief.

The Eighth Route Army also has this kind of machine?
Still more advanced?

How can it be!

But think about it, the two mathematicians think this is entirely possible, for example, Wang Xuexin knows it?
The reason why they don't know is probably just because it is a classified military project.

Thinking of this, mathematicians are both proud and ashamed.

I am proud that Huaxia is also able to lead the sun without setting, and it is still in the field of scientific innovation, which has never happened before.

Ashamed, they thought for a long time that they were at the top in the field of mathematics in China, even if they were not at the top, they were at the forefront. Now it seems... this idea is really ridiculous.

However, what shocked the two mathematicians was yet to come.

There are two mathematicians, one is Ban Haolin and the other is Chen Jiefeng. Both of them are middle-aged and have taught in well-known universities in China. They are quite prestigious in the Chinese mathematics circle.

After they invested in the research and development of the relay computer with Joan, it felt like they had opened up a new field and opened the door to a new world... In fact, this is a new world, and it will change this world in the future.

This made the two excited, and at the same time felt their own smallness and backwardness.

On this day, Joan and they were discussing how many relays would be needed for a group...which determined the scope of the computer calculation.

Joan thinks 32 should be used but the two mathematicians advocate 16.

"32 bits can accomplish more tasks!" Joan said: "The relay is much smaller than the 'Christopher', and the power consumption is also smaller, especially faster. If you can't calculate a larger number, the increase in speed is useless. It means so much!"

"Although you are right, Joan!" Ben Haolin objected: "You should know that the risk of relay work is very high, and 32 bits means that we need at least double the parts, and the risk and maintenance difficulty also doubles !"

This is determined by the working characteristics of the relay. As long as there is a problem with one relay, the whole machine cannot operate normally, so the more parts there are, the greater the risk.

"But it's still worth a try!" Joan insisted: "Only 32 bits can meet most of the computing needs!"

"But 'Christopher' is a group of 16!" Chen Jiefeng was puzzled by this.

"That's why we know it's not enough!" Joan said, "Not enough!"

At this moment, Wang Xuexin strolled into the air-raid shelter, and walked forward in doubt when he heard their quarrel.

Joan breathed a sigh of relief as if she had found a savior, and shouted to Wang Xuexin: "Comrade leader, you came just in time, I want to hear your opinion!"

Wang Xuexin was nervous at the beginning, because he would not be able to understand the problems discussed by mathematicians as long as they were a little more profound... Mathematics was what I was most afraid of when I was in college.

But since he had already hit the muzzle of the gun, he couldn't run away, so Wang Xuexin could only bite the bullet.

After listening to the narrations from both sides, Wang Xuexin basically understood.

This is actually because the sun never sets and China's demand for computers is different.

The sun never sets R&D computer has more data to process, so it needs a computer with more bits and a wider range of calculations.

As for Huaxia, at least so far, the role of computers is to decode.

For Huaxia, where the industry has not developed much, 16-bit computing is enough, even if Wang Xuexin wants to move it to missiles in the future.

"If we need to improve the calculation accuracy!" Joan continued to persuade: "Of course we must expand to 32 bits, otherwise there will be a lot of trouble!"

"Computational accuracy?" Wang Xuexin was taken aback for a moment, and then asked, "Joan, have you heard of floating-point arithmetic?"

"Floating-point arithmetic?" Joan was confused: "What is that?"
