Method

doubleroundDecimal(double x, int d)
Rounds the number off to a given number of significant digits. 
if ((d > 0) && (x != 0)) {
    double factor = Math.pow(10, Math.floor(log10(Math.abs(x))) - d + 1);
    x = Math.rint(x / factor) * factor;
return x;
doubleroundDecimals(double d, int decimalPlaces)
round Decimals 
int j = (int) (d * Math.pow(10, decimalPlaces));
return j / Math.pow(10, decimalPlaces);
doubleroundDecimals(double x, int decimals)
Rounds a double to specified number of decimal places. 
if (decimals > 9)
    return (Math.ceil(x * decimals) / decimals);
double z = 1;
for (int i = 1; i <= decimals; i++)
    z *= 10;
return (Math.ceil(x * z) / z);
introundDiv(double a, double b)
Dividieren und dann das Ergebnis runden. 
return round(a / b);
doubleroundDouble(double d)
round Double 
int c = 10;
int temp = (int) ((d * Math.pow(10, c)));
return (((double) temp) / Math.pow(10, c));
doubleroundDouble(double d)
round Double 
return (double) (int) d;
doubleroundDouble(double d, int decimals)
round Double 
long tempD = (long) (d * Math.pow(10, decimals));
return tempD / (Math.pow(10, decimals));
StringroundDouble(double d, int place)
round Double 
if (place <= 0)
    return String.valueOf((int) (d + ((d > 0) ? 0.5 : -0.5)));
String s = "";
if (d < 0) {
    s += "-";
    d = -d;
d += 0.5 * Math.pow(10, -place);
...
doubleroundDouble(double d, int places)
Rounds a double to a set number of decimal places 
return Math.round(d * Math.pow(10, (double) places)) / Math.pow(10, (double) places);
doubleroundDouble(double num, int precision)
round Double 
return ((double) Math.round(num * pow(10, precision))) / (pow(10, precision));
