No. The point is this plain wrong argument:

The complexity is given by the sample rate. It doesn't change, so the complexity also doesn't change. You don't magically get fuller sound by using multiplication instead of division. It is way more complicated (see my last post).

all that doesn't proof any kind of "fuller sound" some kind of magic compressor... i mean "fuller sound" just because of using a multiplikation instead of a division somewhere inside any algorithm is just pure nonesense... if you are talking about optimizing cpu usage, ok, everybody knows that a division is slower. thats not big news here, it was discussed hundreds of times, but it never will make the sound any "fuller" what should that mean btw? does it double the samplerate? does it boost the bass? does it imitata some analog compression?.... so there is no big mwuhahaha about using a multiplikation instead of a division. also if it changes the result in precision, show me, than we can talk about different results in sound.

Multiplication is better for sound! The only correct answer is not the perfection of the computer processor.
Multiplication is slower and more accurate.
  therefore, interference from the hard drive, cooler, power, distort less.

This does not apply to programming languages.
This applies to ones and zeros.

The flow rate of electrons in the integrated circuit processor.

This is not related to programming at all.

When processors become quantum, this law will not exist

Ok, now we are getting into ridiculous territory. So we are talking about ones and zeros now? Try this:

https://www.calculator.net/binary-calculator.html

Its a binary calculator. The deepest in the electronic circuit you can get.

If you divide 8 which is 1000 in binary by 2 which is 10 you get the binary number 100 which is 4.
Now if you multiply 2 (binary 10), with 2 (binary 10), you also get 100 which is 4. There is no difference!
The final calculation in your computer will be 100 either way.

What you guys are talking about is called optimization. Instead of dividing you can multiply. Instead of writing x^2 you can write x*x. Instead of writing 2x you can write x+x which is faster. It doesnt magically make the sound better. If this were the case, it would be all over the any digital platform like image processing. If you use a multiplication on a formula instead of dividing it doesnt magically make the pixels look better.

Hi Adam!

I respect you as a musician and a good person.

BUT I do not agree with you,
You are talking about the digital path, and a calculator.

I mean electricity.
I'm talking about the molecules themselves things and wildlife!


Even a tektronix oscilloscope makes mistakes! Such is the

Even brain neurons multiply better than divide. When rotating red and white, a person sees pink. This proves this phenomenon, but it is difficult to explain!

I think i get your gist - but also division has a special sound which might be good for some music.
multiplication is not the means of it all - it's simpler in hardware, but doesn't the extra complexity used in division add some certain distortions which could be usable for some kinds of music? I very well think so!\

Did you know instead of subbing in a ramp, you can do fmod, which changes the oscillators harmony slightly different?
I want to propose that these math operations do different sounds, not just bad and good, just different effect on sound, can we agree on that?
