Method

BigDecimalround(BigDecimal b, int precision)
round a number to an arbitrary precision based on http://www.crazysquirrel.com/computing/java/basics/rounding.jspx 
 * BigDecimal(d); 
 * b.scale() + precision ), RoundingMode.HALF_UP); 
 * b.round(context).doubleValue(); double exp=Math.pow(10, precision);
 * d*=exp; long dlong=Math.round(d);
 * 
 * return dlong/exp; }

public static BigDecimal round(BigDecimal b, int precision) {
    ...
BigDecimalround(BigDecimal d, int decimalDigits, RoundingMode rmode)
Round the passed BigDecimal so that only decimalDigits remain after the point. 
return d.round(new MathContext(intDigits(d) + decimalDigits, rmode));
doubleround(BigDecimal d, int decimalPlace)
round 
d = d.setScale(decimalPlace, BigDecimal.ROUND_HALF_UP);
return d.doubleValue();
longround(BigDecimal decimal)
Rounds the value to a long using java.math.RoundingMode#HALF_UP 
return decimal.setScale(0, ROUNDING_MODE).longValue();
BigDecimalround(BigDecimal decimal)
round 
return new BigDecimal(Math.round(decimal.doubleValue()));
BigDecimalround(BigDecimal decimal, int decimalDigits)
round 
BigDecimal scale = new BigDecimal(Math.pow(10, decimalDigits));
return new BigDecimal(Math.round(decimal.multiply(scale).doubleValue())).divide(scale);
BigDecimalround(BigDecimal decimal, int precision)
Rounds the given decimal to the given precision using the default rounding algorithm. 
return round(decimal, precision, null);
BigDecimalround(BigDecimal dividend, int divisor)
round 
if (dividend == null || divisor == 0) {
    return dividend;
BigDecimal remainder = dividend.remainder(BigDecimal.valueOf(divisor));
return remainder.equals(BigDecimal.ZERO) ? dividend
        : remainder.intValue() < divisor / 2 ? floor(dividend, divisor) : ceiling(dividend, divisor);
BigDecimalround(BigDecimal initData, int scale)
round 
if (initData == null) {
    return null;
return initData.setScale(scale, BigDecimal.ROUND_HALF_UP);
BigDecimalround(BigDecimal money, int scale)
round 
if (scale < 0) {
    throw new IllegalArgumentException("The   scale   must   be   a   positive   integer   or   zero");
BigDecimal one = new BigDecimal("1");
return money.divide(one, scale, BigDecimal.ROUND_HALF_UP);
