My dear Roman Numeral Converter is dysfunctional:

function convert(num) {

   var rechim = num.toString().split("");
   var l = rechim.length - 1;
   console.log(rechim);
   if (rechim[-1] === 1) {rechim.splice(-1,1, "I")}
   else if (rechim[-1] === 2) {rechim.splice(l-1,1, "II")}
   else if (rechim[-1] === 3) {rechim.splice(l-1,1, "III")}
   else if (rechim[-1] === 4) {rechim.splice(l-1,1, "IV")}
   else if (rechim[-1] === 5) {rechim.splice(-l1,1, "V")}
   else if (rechim[-1] === 6) {rechim.splice(l-1,1, "VI")}
   else if (rechim[-1] === 7) {rechim.splice(l-1,1, "VII")}
   else if (rechim[-1] === 8) {rechim.splice(l-1,1, "VIII")}
   else if (rechim[-1] === 9) {rechim.splice(l-1,1, "IX")}
   else if (rechim[-1] === 0) {rechim.splice(l-1,1,"")}

     if      (rechim[-2] ===1) {rechim.splice(l-2,1,"X")}
     else if (rechim[-2] ===2) {rechim.splice(l-2,1,"XX")}
     else if (rechim[-2] ===3) {rechim.splice(l-2,1,"XXX")}
     else if (rechim[-2] ===4) {rechim.splice(l-2,1,"Xl")}
     else if (rechim[-2] ===5) {rechim.splice(l-2,1,"L")}
     else if (rechim[-2] ===6) {rechim.splice(l-2,1,"LX")}     
     else if (rechim[-2] ===7) {rechim.splice(l-2,1,"LXX")}     
     else if (rechim[-2] ===8) {rechim.splice(l-2,1,"LXXX")}     
     else if (rechim[-2] ===9) {rechim.splice(l-2,1,"XC")}      
     else if (rechim[-2] ===0) {rechim.splice(l-2,1,"")}


     if      (rechim[-3] ===1) {rechim.splice(l-3,1,"C")}
     else if (rechim[-3] ===2) {rechim.splice(l-3,1,"CC")}
     else if (rechim[-3] ===3) {rechim.splice(l-3,1,"CCC")}
     else if (rechim[-3] ===4) {rechim.splice(l-3,1,"CD")}
     else if (rechim[-3] ===5) {rechim.splice(l-3,1,"D")}
     else if (rechim[-3] ===6) {rechim.splice(l-31,"DC")}     
     else if (rechim[-3] ===7) {rechim.splice(l-3,1,"DCC")}     
     else if (rechim[-3] ===8) {rechim.splice(l-3,1,"DCCC")}     
     else if (rechim[-3] ===9) {rechim.splice(l-3,1,"CM")}      
     else if (rechim[-3] ===0) {rechim.splice(l-3,1,"")}
     console.log(rechim);
   return rechim.join("");
  }
convert(36);

surprising result: "36"

@SaintPeter

@navyvel Goodness. A loop would be helpful

Prateek Karnal

@Equlnox

can anyone suggest me a good text editor for developing html programs?

Rex Schrader

@SaintPeter

@navyvel In general, you need to think about what is really happening when you're converting a number to a roman numeral:
Say I'm converting 2015

2000 is greater than 1000 (M), and I can get 2 in there, so I start with MM
2015 - 2000 = 15
15 is not greater than 500 (D), 100(C), or 50(L)
15 is greater than 10 (X) and I can fit 1 in, so now I have MMX
15 - 10 = 5
5 === 5 (V) and I get one, so now I have MMXV
5 - 5 = 0, so I can stop

@Equlnox Atom is pretty nice. It has a ton of plugins, too, to make your life easier

@tanasic

@Equlnox u can also try microsofts new visual studio code.. it is pretty fast.. has their intelli sense and what not

i've switched from atom to visual code... much faster

@Equlnox https://code.visualstudio.com/

Kouty

@koouty

@SaintPeter I think that to convert the decimal number into a string and begin with the index of the sliced string to a roman character. Is it not faster?
2015 is 2 -> MM
0 -> ""
1 -> X
5 -> 5
that is MMXV;
No good?

@SaintPeter

@navyvel The problem is that values like 50 don't have a place value.

@navyvel IE: 75

Kouty

@koouty

@SaintPeter
Why not? 7 -> LXX
and 5 -> V
75 -> LXXV no?

Rex Schrader

@SaintPeter

@navyvel Or 500 - consider this:

74 is not greater than 1000, 500, 100, but it is greater than 50, so "L"
74 - 50 = 24
24 is greater than 10, and I can fit 2, so "LXX"
24 - 20 = 4
4 = 4 (IV), so "LXXIV"
4-4 = 0 so we're done

@navyvel Well, then you get into the situation that you have to spell out every possible roman value for each digit. Seems like a drag. Your code will be huge.

Kouty

@koouty

@SaintPeter Right You're right. I agree with you.
But in my enormous code Is an error, why the split method don't replace the digits in Upper case letters? Can your explain this?

Rex Schrader

@SaintPeter

@navyvel The problem may be that it's a string, not a number

pantelis

@pantelisB

Hello!!!

KofiAkorli

@KofiAkorli

@pantelisB hiii

Rex Schrader

@SaintPeter

@navyvel You can use parseInt to turnit into a number

Kouty

@koouty

@SaintPeter Sorry if I'm a bore... but for me the number will be turned into a string, through the toString method, and next sliced in an Array, and next the Array were spliced with suppressed digit-characters and replaced Up case letters.

Rex Schrader

@SaintPeter

@navyvel Right, so each digit needs to be converted to a number with parseInt

@navyvel Or you need to compare it to a string

@navyvel IE: digit === '1' or digit === '2'

Kouty

@koouty

@SaintPeter Yees
I understand, you're good, the === was out of my mind
Thank's so much and congratulation for the patience!

@Philosophist

Hello help room. Can I get some feedback on the portfolio web page zipline? I'm feeling a bit lost on what to do next. http://codepen.io/Philosophist/pen/xwZGar

Like, how do I get the horizontal break lines to be clear and how do I push the content to not bury itself behind the nav bar?

Sasa

@tanasic

margins/padding I guess

@DavidBouw

@Philosophist Nitpicking, but <hr> does not require a closing tag

Oh, cool. I think I just figured out opacity for the hr. How do I get it to be longer like the one I'm reverse engineering? http://codepen.io/ThiagoFerreir4/full/eNMxEp
