Method

doublegetRoundedValue(double doubleValue)
Rounds off the double value up to 2 decimal digits. 
DecimalFormat decimalFormatter = new DecimalFormat(ROUND_UPTO_TWO_DECIMAL_FORMAT);
double roundedValue = Double.parseDouble(decimalFormatter.format(doubleValue));
return roundedValue;
StringgetRoundedValue(double value)
Get rounded double value, according to the value of the double. 
StringBuffer decimalFormatBuffer = new StringBuffer(TWO_DECIMALS_FORMAT);
double compareValue = 0.1;
while (value > 0 && value < compareValue && !decimalFormatBuffer.toString().equals(MAX_DECIMALS_FORMAT)) {
    decimalFormatBuffer.append(DECIMALS_FORMAT_TOKEN);
    compareValue = compareValue * 0.1;
DecimalFormat decimalFormat = new DecimalFormat(decimalFormatBuffer.toString());
return decimalFormat.format(value);
...
Stringround(double d, int n)
round 
if (d == 0) {
    d = 0;
if (n < 0) {
    n = 0;
String str = "";
if (n == 0) {
...
doubleround(double d, int p)
Round a double to p decimal places 
String format = "0.";
for (int i = 0; i < p; i++)
    format += "0";
DecimalFormat twoDForm = new DecimalFormat(format, new DecimalFormatSymbols(Locale.US));
return Double.valueOf(twoDForm.format(d));
doubleround(double dValue)
round 
NumberFormat currencyFormat = NumberFormat.getCurrencyInstance();
double fractionMultiplier = Math.pow(10.0, currencyFormat.getMaximumFractionDigits());
return Math.rint(dValue * fractionMultiplier) / fractionMultiplier;
Stringround(double number)
Rounds the given number to two decimals. 
DecimalFormat df = new DecimalFormat("#.##");
df.setDecimalFormatSymbols(DecimalFormatSymbols.getInstance(Locale.US));
df.setRoundingMode(RoundingMode.HALF_UP);
return df.format(number);
Stringround(double unrounded, int precision)
round 
DecimalFormat df = new DecimalFormat("####0.##########");
BigDecimal bd = new BigDecimal(unrounded);
BigDecimal rounded = bd.setScale(precision, BigDecimal.ROUND_HALF_UP);
return df.format(rounded.doubleValue());
Stringround(final double value)
round 
return FORMAT_PRECISION_2.get().format(value);
StringroundAlloc(Double alloc)
round Alloc 
return new DecimalFormat("#.#").format(alloc);
StringroundAndTruncate(double rawValue, int precision)
round And Truncate 
DecimalFormat df = new DecimalFormat();

df.setMinimumFractionDigits(precision);
df.setMinimumIntegerDigits(1);
return df.format(rawValue);
