Well, gives the ability to convert numbers into roman numbers and vice versa:

PHP Code:


		
			
public function romanToNumber(roman) {
  temp.table_l = {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"};
  temp.table_n = {1000,900,500,400,100,90,50,40,10,9,5,4,1};
  temp.n = 0;
  for(temp.i = 0; i < roman.length(); i ++) {
    if (roman.substring(i, 2) in table_l) {
      n += table_n[table_l.index(roman.substring(i, 2))];
      i ++;
    }else n += table_n[table_l.index(roman.charat(i))];
  }
  return n;
}
public function numberToRoman(number) {
  temp.table_n = {1000,900,500,400,100,90,50,40,10,9,5,4,1};
  temp.table_l = {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"};
  temp.out = "", temp.number2 = number;
  for(temp.n : table_n) {
    while(number2 >= n) {
      number2 -= n;
      out @= table_l[table_n.index(n)];
    }
  }
  return out;
}

Example:

PHP Code:


		
			
function onCreated() {
  echo(numberToRoman(947));
  echo(romanToNumber("CMXLVII"));
  /*
  CMXLVII
  947
  */
  echo(numberToRoman(2008));
  echo(romanToNumber("MMVIII"));
  /* 
  MMVIII
  2008
  */
  echo(numberToRoman(romanToNumber("MMVIII")));
  // MMVIII
}

anyways, enjoy?

Ace, this will be pretty cool for implementing a sort of RP thing with numbers. I don't really see it making a big gameplay impact as not many know how to translate roman numerals, but I guess it's still cool, and new!

PHP Code:


		
			
  temp.table_n = {1000,900,500,400,100,90,50,40,10,9,5,4,1};
  temp.table_l = {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"};

PLEASE use multi-dimensional arrays :cry:

Aw be quiet :/ ... its good enough for what it's doing.

naw, I don't see a reason for it..

Naw. Using multi-dimensional arrays in this case makes it just alot more complicated since you have to divide the index by two for find the correct number, then plus 1 to find the letter( and by using multi dimensional arrays you can't use the
for(member : array) loop because of indexes being wrong, and you to use an extra variable to count the index), so... Nope. Using multi-dimensional arrays in this case just makes it more complicated then it needs too.

What?

PHP Code:


		
			
temp.table = { { 1000, "M" }, { 900, "CM" } };

for ( temp.n : temp.table )

{

  temp.num = temp.n[0];

  temp.letter = temp.n[1];

}

I think you misunderstand the concept of multi-dimensional arrays.

And you can certainly use for (needle: haystack) with a multidimensional array.

Ninja edit btw (err, I started to think about something I did earlier, then I realised you meant {{foo}, {bar}} arrays (multi-dimensional arrays), realised that after like 10 secs after posting that post xD)

Anyways

PHP Code:


		
			
public function numberToRoman(number) {
  temp.table = {
    {1000,900,500,400,100,90,50,40,10,9,5,4,1},
    {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"}
  };
  temp.out = "", temp.number2 = number;
  for(temp.n : table[0]) {
    while(number2 >= n) {
      number2 -= n;
      out @= table[1][table[0].index(n)];
    }
  }
  return out;
}
public function romanToNumber(roman) {
  temp.table = {
    {1000,900,500,400,100,90,50,40,10,9,5,4,1},
    {"M","CM","D","CD","C","XC","L","XL","X","IX","V","IV","I"}
  };
  temp.n = 0;
  for(temp.i = 0; i < roman.length(); i ++) {
    if (roman.substring(i, 2) in table[1]) {
      n += table[0][table[1].index(roman.substring(i, 2))];
      i ++;
    }else n += table[0][table[1].index(roman.charat(i))];
  }
  return n;
}

And, the reason why I posted that I posted was because I thought I did something like that, but I did:

PHP Code:


		
			
temp.table = {
       1, "I",
       5, "V",
      10, "X",
      50, "L",
     100, "C",
     500, "D",
    1000, "M"
  };

and that popped into my mind when I saw your post Chris, sorry for the misunderstanding xD

And, some other version of it (romanToNumber()) under:

PHP Code:


		
			
public function romanToNumber(number) {
  temp.table = {
       1, "I",
       4, "IV",
       5, "V",
       9, "IX",
      10, "X",
      40, "XL",
      50, "L",
      90, "XC",
     100, "C",
     400, "CD",
     500, "D",
     900, "CM",
    1000, "M"
  };
  temp.number2 = number;
  temp.out = "";
  for(temp.i = table.size()-1; i > -1; i -= 2;) {
    temp.number3 = 0;
    while(number2 >= table[i-1]) {
      if (number2 > 0) {
        number2 -= table[i-1];
        out @= table[i];
      }
    }
  }
return out;
}
