Method

doubleround(double val, long dec)
round 
double erg, p;
p = Math.pow(10.0, (double) dec);
erg = Math.floor(val * p + 0.5) / p;
return erg;
intround(double valor)
DOCUMENT ME! 
if ((valor - ((int) valor)) >= 0.5)
    return (((int) valor) + 1);
else if ((int) valor == 0)
    return 1;
else
    return (int) valor;
intround(double value)
round 
int roundedValue = value > 0 ? (int) (value + 0.5) : -(int) (Math.abs(value) + 0.5);
return roundedValue;
doubleround(double value)
round 
return Math.round(value * 10000) / 10000.0;
intround(double value)
Rounds a double to the next nearest integer value. 
int roundedValue = value > 0 ? (int) (value + 0.5) : -(int) (Math.abs(value) + 0.5);
return roundedValue;
longround(double value)
Rounds the given double value 
if (value < 0) {
    return (long) (value - 0.5);
} else {
    return (long) (value + 0.5);
longround(double value)
Rounds the given double value 
if (value < 0) {
    return (long) (value - 0.5);
} else {
    return (long) (value + 0.5);
doubleround(double value)
round 
final double NUMBER_OF_DIGITS = 1E5;
return (double) Math.round(value * NUMBER_OF_DIGITS) / NUMBER_OF_DIGITS;
Stringround(double value, double decimalplaces)
Rounds value. 
double mult = Math.pow(10.0, decimalplaces);
return String.valueOf(Math.round(value * mult) / mult);
doubleround(double value, double factor)
Round the value to the nearest factor. 
return (Math.round(value / factor) * factor);
