fucking fuck

Dearest /prog/,
This is an actual snippet of production code from a jsp application used by the US health-care system, which I have the misfortune to be developing on. This is not a joke.

public String rnd(double e, double d, int numDigits)
{
    String t;
    int tempDouble;
    double f;
    //e=16.47;
    //d=47.023;
    //out.print(e + " + " + d);
    f= e / d;
    //out.print("<br>" + f);
   
    //out.print("<br>f=" + f);
    tempDouble=(int)((f)* Math.pow(10,numDigits+1));
    //out.print("<br>tempDouble=" + tempDouble);
    f=(double)tempDouble;
    f=f/10;
    f=Math.round(f);
    //out.print("<br>f=" + f);
    //out.print("<br>" +tempDouble + " " + f/Math.pow(10,numDigits));

    t=Double.toString(f/Math.pow(10,numDigits));
    if (t.substring(t.indexOf('.'),t.length()).length() < numDigits+1)
        t=t+'0';
    //out.print("<br>" + t);
    if (t.compareTo("0.00")==0)
        t="0.0";
    return t;
}

Found you're problem.
