Faster calculations

[Shamestone]

Hello, it's very important, I didn't know where to post this, I came to a very strange thing. We can have in RAM memory answers to calculations, for example: 4 328,7 - 528,43 = 3 800,27. But I asked Copilot and ChatGPT about this, and they told me that someone already thought about this. However, I don't want to talk about this, I came to so- called Multidigitality. We can use "thinking" in calculations, for example have every calculation on numbers from 0 to 9 in memory. Then computer makes many of them, but has them in RAM memory, it's much faster. And computer writes them binary, see:



4 328,7 - 528,43 = ???,

We have to perform 10 - 3, because the first number has nothing, and make 6 from 7,

The result will be in memory written in binary, that is 7 in our system,

We will have 6 - 4, that is 2 binary,

And then 8 - 8 = 0,

Then 2 - 2 = 0,

3 - 5, we have higher number, so we have to add 10 to 3,

That is 13 - 5 = 8,

We write these numbers from right to left, so:

3 800,27.

Happy Christmas!

This kind of thing is interesting to experiment with. The performance would depend on the language used.

If it was me, I'd write a program that used the built-in subtract, and another that used the new idea.

Run the programs on the same hardware, and the same random numbers. See how many subtracts each program can do in 5 minutes.
