| Lets get to the nub of the issue. Basically you want to get rid of negative numbers. Is that a fair summary of what you're after? Hmm... no. I don't want to get rid of negative numbers. I want to perfect his representation, and I think that Spiderpig already solved it for negative numbers. What you... |

| I made 2 friends when I was in school. We studied the same things, so we shared time, and had common things to do, so we were friends, even when I was poor at small talk, because my poor social skills were camouflaged by the activities. It ended and each one of my friends moved to another city. I fe... |

| Since real numbers also are pair of numbers, the same trick could be used to get rid of the radix point. >=→=1 <=←=-1 ^=0.1 ˅= ^ =-0.1 ┐= 1 =1.1 └= 1 =-1.1 ┘=1-0.1=0.9 ┌=-1+0.1=-0.9 Hmm, no, I found that that method doesn't works, because it still needs a ra... |

| For example, if base is -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, which we can represent with the symbols B, C, D, A, 0, 1, 2, 3, 4, 5 or for clarity: 4 , 3 , 2 , 1 , 0, 1, 2, 3, 4, 5 There’s a problem with an even base like 10, though: it makes the system unbalanced, and this does cause arithmetic to be m... |

I know that I did not presented a strictly coded problem, but some interpretations of my post looks to me illogical and arbitrary. ... |

Why would that matter? -It matters because is the point of the thread. -It matters because has important applications, like optimizing computer resources in programming. -It matters because it may ... |

Why?
Please, give a correct, and well presented answer.
Spiderpig gave good answers to the problem presented on the first post. His answer to the problem of sign was very good. |

| What is being wasted? Unused combinations of the symbols are wasted. For example, the traditional decimal system for integers have 11 symbols, which are "0","1","2","3","4","5","6","7","8","9","-", but not any combination of those symbols is utilized. 34--43--- means nothing. You might as well say ... |

| But the system efficiency is ruined when we have decimals, or negative numbers. With these we have 2 extra symbols, the "." and the "-". The "-" can only be placed once, and only on one position. Meanwhile the "." can be on any place, but can be present only once. That's wasteful. That isn't really... |

| I don’t know if you can “efficiently” get rid of the radix point (that’s how you call the character separating the integer and fractional parts without referring to a specific base), because, in a positional system where digits are weighted with all integral powers of the base, you need a way to ma... |

| I don’t think it’s so complicated, but, at any rate, I was answering the OP’s question. After thinking a bit more about this, the radix point can indeed be done away with easily: instead of assigning the weights the usual way, as powers of the base with exponents ranging from right to left, from -&... |

I suspect that is fair and convenient to assume that 7=07=000007. I other words, any number is supposed to have any quantity of zeros to the left. |

| Doing arithmetic with numeral sequences that have a mix of "positive digits" and "negative digits" would become painfully complicated. One minus sign to the left takes care of the matter a binary minus in the same position that could have been occupied by "+" does the trick. What you are suggesting... |
