Format Double as Fraction [closed]

Answer 1

My code looks like this.

public static int gcd(int a, int b)
    {
        if (b == 0)
            return a;
        else
            return gcd(b, a % b);
    }

public static String doubleToStringFraction(Double d)
    {
        StringBuffer result = new StringBuffer(" " + ((int) Math.floor(d)));
        int whole = (int) ((d - Math.floor(d)) * 10000);
        int gcd = gcd(whole, 10000);
        result.append(" " + (whole / gcd) + "/" + 10000 / gcd + " ");
        return result.toString();
    }
