You are going about it backwards. Ignore compression until you have solved the expansion.

Your search for reversible data compression will be never-ending if you do not first look for ways to expand compressed data.

### Re: Squares

When pigs will fly, albert may find a de-compressor code that will recover information lost during compression! GM pigs are possible. At about the time that pigs fly, Albert will realise the theoretical impossibility of finding a reversible data compression algorithm based on randomly selected hash...

You use the same seed "0" every time. Use Randomize once at the start. Screen 19 Randomize Dim As String vals(0 To 31) Dim As String match Dim As Longint count Dim As String n1 For a As Longint = 0 To 31 Step 1 n1 = Bin(a) count = 0 Do match="" For b As Longint = 1 To Len(n1) mat...

You have lost information so you cannot always reverse it.

### Re: Squares

I came up with an idea for corporate board members... Companies have between 7 and 31 board members.. I believe "The Peter Principle", 1969, demonstrated that having more than 7 members on a board or committee makes it unmanageable and unproductive. https://en.wikipedia.org/wiki/Peter_pri...

@albert. We really cannot help you do what we can prove is impossible. You will be more successful if you contact the ARRL in your city. Tell them you want to get your amateur radio licence. Morse code is not required. You have all the skills needed. A good start would be to contact; John Kitchens, ...

### Re: Squares

@Richard It requires 5 decimal places of precision to get to 65,535... 17 bits + 4 bits comes out to 21 bits.. 5 places goes to 291,465.. @Albert. That is not a question. You are having a psychotic episode. Take your medication. You have insufficient algebra skills to write software without asking ...

I don't have an FCC license , you have to be proficient in Morse code , and i had difficulty learning Morse code...So i didn't get the license.. All Morse code was dumped from the Ham licence in the USA back in early 2007. I only took "General Math" in high school , i didn't take algebra ...

### Re: Squares

@Albert. It is now long past the time that you should have stopped expecting to stumble upon a herd of Unicorns, while looking at patterns in numbers and formulas. Most 12 year old school students understand that there is a field of mathematics called algebra. They know that algebra makes it possibl...

### Re: Squares

@ Albert. n = int( rnd * 6553 5 ) mod 256 n = Int( Rnd * 6553 6 ); generates random 16 bit Uintegers from 0 to 6553 5 . x = n Mod 256; keeps only the 8 bits on the right and throws away the most significant 8 bits. Those missing bits are y = n \ 256, they cannot be recovered. LoByte(n) and HiByte(n)...

### Re: Squares

Note: If the question is not very understandable or changing, we can hardly help. You guys; I'm trying to round the 16 bit input ( 0 to 65535) to 1 or 2 decimal digits , and then try to recreate the input with just those 2 digit places. No one can possibly help if it is both mathematically impossib...
