That is your problem.
Go away, and don't come back until you have studied math.

Re: Squares

Is there a way to undo the MOD 128 ?? ( I'm not understanding how the MOD works... ) MOD destroys the most significant part of an integer, and just keeps the remainder. Real programmers know that MOD is the remainder left after an integer divide. There is no way of reversing MOD, unless the result ...

Re: Squares

I think the Zlib , has AI built-in to foil compression attempts!!! Zlib does not need to use AI, it can rely on your paranoia. Zlib identifies and compresses duplicates. Once that has been done there is no more compression possible. If Zlib output could be further compressed, then Zlib would have d...

Re: Squares

@Richard You told me that ( n2 OR 384 ) would return the number , and include the top 2 bits.. the 128 bit , and the 256 bit.. Now your saying , "it can't be done" ? "You can't undo destruction." I thought you asked how to set a bit if you knew it was a one. In the real world, t...

Re: Squares

I think when you say something “compresses” you actually mean that part of it is “deleted”.
Your belief that you can “uncompress” is really a belief that you can magically “undelete” what has been destroyed.

Re: Squares

@albert If “anything” is a positive integer then; Anything to the power of 0 is one. 2^0 = 1. Anything to the power of 1 is itself. 2^1 = 2. Anything to the power of 2 is the square. 2^2 = 4. Anything to the power of 3 is the cube. 2^3 = 8. That is why the bits in a binary number are numbered starti...

Re: Squares

When you “value MOD 128" you destroyed two bits, they had values of 256 and 128 making a total of 384. If you only remember one of them, then you cannot restore the original value because you have lost the other. "value OR 384" will set the two MSBs, what you call bits 8 and 9. "...

Re: Squares

@Richard If i have a 9 bit binary value and mod it by 128 , how would you recover the value , when you know the 9'th bit is set?? It depends what you mean by the 9'th bit. You could "value OR 128" to set the byte MSB again. But why delete two bits with "value MOD 128" if you are...

Re: Squares

Not SoftRam, but an earlier hardware compression failure that could not be fixed because the code was in ROMs. The board was a PC-XT hardware processor on ISA? bus, DOS, pre-1990, when a HDD could be up to 40 Mbyte.

Re: Squares

I think walking down a virtual isle filled with items would be a good idea.. I imagine a virtual store, with only three aisles of quite different lengths. Aisle 1. Lossless compressors that return everything intact, for use on exact data and executable code. It is a very short aisle, displaying a f...

Re: Squares

@Albert. Cell phones do not use a frequency, they use a whole band by employing spread spectrum techniques and quadrature modulation. That is so far beyond your understanding that it must seem to be magic. Cell phone DSP is not relevant to this website until you write an FB program to simulate a QAM...

Re: Squares

@Albert. What would happen if the GPS or tranceiver on one vehicle failed intermittently, while on a four lane freeway in rush hour? How would you know where the back end of a reversing semitrailer was if the GPS was in the cab? You are having ideas for a tragic fiction. Now you need to write an FB ...
