    Continuing off my previous post

    24 bits are kinda trash for storing numbers through the prime factor format. But 24 bits is even less than ordinary integers, and maybe we can do better. If we allow upto 32 bits (like ordinary ints), then we have 6 more bits for adding in 11 as a prime factor as well as 2 leftover bits. One of those bits could be a sign, allowing for negative numbers. Another could be fucking anything idk.

    Now this way of doing things … isn’t not necessarily too bad, but we could try to improve?

    First, we can store the exponents as a 2’s complement. Search it up. It’s slightly more efficient than storing signed integers. Basically in signed ints, +0 and -0 are stored as 2 seperate numbers even though they are functionally the same. In 2s complement, this is fixed.

    I had 6 bit for the exponent. 1 for the sign. 3 for the powers (upto 7th power). 2 for the roots (upto 4rth root)

    With 2’s complement we can change to 4 bits for the powers and 2 for the roots. This allows the powers to range from -8 to +7

    Which is … wierd? And stupid? I don’t think -8 is a very common power to use. Imagine being able to store 1/256 exactly, but not 13. A better way imo is to go 2 bits for the powers and 2 for the roots. This restricts the powers down to -4 to 3 which isn’t super nice, but has the advantage that prime factors are now stored as 4 bit blocks. This plays nicely with the computer.

    Now I introduce my next trick. Not every prime factor is equal. 2 and 5 are important. So I can give 8 bits to the each of them. That’s 16 bits. Then the remaining 16 bits are divided into 4 other prime factors (3, 7, 11 and 13).

    Quick post Imma continue next mega

    Am trynna concieve of a data type which stores numbers as lists of prime factors.

    Would be fast and exact for multiplication. But too much memory usage. In a dataset with n unique prime factors overall, you need worst case, k*n bits per number (k is the number of bits used to store the exponent of that prime factor).

    Adding fractions to the powers of prime factors would allow it to be very effective in some small range of numbers.

    Upto 10, there are 4 primes numbers. You can use 2 bits for the denominator of the exponent (the root), allowing you to express square, cube and 4rth root (most common). A bit for the sign. 3 bits for the numerator of the exponent (upto 8th power). So k=6 bits

    Total you’d need 24 bits per number.

    Doesn’t than suck for a system that can’t even store the number 11? Well, yes, but also think about how densely packed your grid of numbers is in that small range of 0.1 to 10. Like that’s almost 24 bits of information packed into that range (some numbers are bigger or smaller). If you have say, 2^20 numbers in that range, you get ~1 million numbers in that range. And if you use scientific notation you can get some juice out of this.

    sex and dysphoria mention

    There’s 2 types of sex. Sex were you actually feel pleasure, sex that you’re doing as a gender affirming ritual. My problem is that due to brainworms I really focus on the 2nd type of sex rather than the first time. Most of the time, horny is just not actually pleasurable. It’s just me thinking this makes me womanly. And that feeling goes away right after the horny activities and well, that becomes dysphoric.

    There’s many factors going into what exactly makes me in 1 sex mode vs another. Stress is 100% a big factor. It turns off the pleasure part of sex, and leaves behind only empty gender validation.
