Hello, how are you?

I have to erase those registers that are equal, no matter if one of the number is negtive
For example, in this case I have to eliminate the 2, 3, 5 and 6 register.
I was thinking in pass them to zd format and with that erase the negative symbol but there are negative numbers not to be erased, I have to only erase those that are repeating.
Desired output:

4425480000000299 . -72.00 . 2021-07-19

#1. Plan the logical way: what is the sequence of elementary steps to do what you need? (unrelated to neither SORT, nor whatever else). This is called with the word “algorithm”.
#2. Try to find out the available SORT operations to implement your algorithm.
Otherwise your question sounds as: “Please, do my own job for me!”
BTW, what is the word “register” in your terminology??? 
You are removing 3000.00 and -3000.00
What if there were 3000.00 and 3000.00? They are EQUAL, too!
Etc, etc… 100 questions. Lazy to print all of them - this should be your responsibility to explain this clearly.

This is a question for yourself, not for the forum… |

| I found a way to solve this, I did not ask no-one to do my job, simple give some clue or idea, but well, it seems that everytime I make some question you are here to reproach me something while other forum members simple give some idea or clue to research. As I said, i do not want code, simple a clue, is evident that I search the forum and I did not find any casuistry similar to this. |

I gave you the clear idea of two obvious steps. You decided to ignore it; it’s up to you. |
