I'm having some issues with a conversion algorithm I'm working in.
The this is that it works fine unless i put a round number like 100, 200, 300, NNN...
Any clue what could it be?

Method code:

```
 public static String decimalToRomano(int decimal) {
        int x = 0;
        int cent, dece, unid;
        cent = x / 100;
        x = decimal % 100;
        dece = x / 10;
        unid = decimal % 10;
        String romano = "";
        switch (cent) {
            case 1:
                romano = romano + "C";
                break;
            case 2:
                romano = romano + "CC";
                break;
            case 3:
                romano = romano + "CCC";
                break;
            case 4:
                romano = romano + "CCCC";
                break;
            case 5:
                romano = romano + "D";
                break;
            case 6:
                romano = romano + "DC";
                break;
            case 7:
                romano = romano + "DCC";
                break;
            case 8:
                romano = romano + "DCCC";
                break;
            case 9:
                romano = romano + "DCCCC";
                break;
        }
            switch (dece) {
            case 1:
                romano = romano + "X";
                break;
            case 2:
                romano = romano + "XX";
                break;
            case 3:
                romano = romano + "XXX";
                break;
            case 4:
                romano = romano + "XXXX";
                break;
            case 5:
                romano = romano + "L";
                break;
            case 6:
                romano = romano + "LX";
                break;

                break;
            case 8:
                romano = romano + "LXXX";
                break;
            case 9:
                romano = romano + "LXXXX";
                break;
        }
        switch (unid) {
            case 1:
                romano = romano + "I";
                break;
            case 2:
                romano = romano + "II";
                break;
            case 3:
                romano = romano + "III";
                break;
            case 4:
                romano = romano + "IIII";
                break;
            case 5:

                break;
            case 7:
                romano = romano + "VII";
                break;
            case 8:
                romano = romano + "VIII";
                break;
            case 9:
                romano = romano + "VIIII";
                break;
        }
        return romano;
    }
