Description

The list of methods to do BigDecimal Round are organized into topic(s).

Method

BigDecimalrounded(BigDecimal amount)
Rounds an amount to two decimal places. 
return amount.setScale(DECIMALS, ROUNDING_MODE);
DoubleroundHalfUp2Scale(BigDecimal value)
round Half Up Scale 
if (value == null)
    return null;
BigDecimal bd = value.setScale(2, BigDecimal.ROUND_HALF_UP);
return bd.doubleValue();
BigDecimalroundImpl(final BigDecimal number, final int minFractionDigits, final int maxFractionDigits, final RoundingMode mode)
round Impl 
final int scale = number.scale();
if (scale < minFractionDigits) {
    return number.setScale(minFractionDigits, mode);
if (scale > maxFractionDigits) {
    return number.setScale(maxFractionDigits, mode);
return number;
...
BigDecimalroundingError(final BigDecimal dividend, final BigDecimal divisor, final int roundingMode)
Calculates the rounding error when dividend is divided by divisor 
return dividend.subtract(dividend.divide(divisor, divisor.scale(), roundingMode).multiply(divisor));
BigDecimalroundOff(final BigDecimal amount)
This method is a utility method, which takes a BigDecimal and rounds that to 0 places. 
return amount.setScale(DECIMALS, ROUNDING_MODE);
BigDecimalroundPrice(BigDecimal price, BigDecimal ticksize)
Rounds the specified price to the specified tick size 
return roundPrice(price, ticksize, ticksize.scale());
BigDecimalroundTo(final BigDecimal bd, final int numberOfDecPlaces, final int finalScale)
returns a new BigDecimal with correct scale after being round to n dec places. 
return setScale(setScale(bd, numberOfDecPlaces, BigDecimal.ROUND_HALF_UP), finalScale);
BigDecimalroundToMSDecimal(BigDecimal sourceDecimal)
round To MS Decimal 
BigInteger sourceDecimalIntComponent = sourceDecimal.unscaledValue();
BigDecimal destinationDecimal = new BigDecimal(sourceDecimalIntComponent, sourceDecimal.scale());
byte roundingModel = 4;
validateDecimalMinMax(destinationDecimal);
BigInteger allWordBigInt = destinationDecimal.unscaledValue();
if (allWordBigInt.bitLength() > 96) {
    destinationDecimal = destinationDecimal.round(new MathContext(29));
    if (allWordBigInt.bitLength() > 96) {
...
BigDecimalroundUp1(BigDecimal number)
round Up 
return number.setScale(0, RoundingMode.UP);
BigDecimalvalueOfBigDecimalRounding(double d1, int decimalPrecision)
value Of Big Decimal Rounding 
BigDecimal bd = new BigDecimal(d1);
MathContext mc = new MathContext(decimalPrecision, RoundingMode.HALF_UP);
return bd.round(mc);
