Method

voidbigDecimalProperty(ObjectNode node, String propertyName, BigDecimal propertyValue)
Sets the value of a property for a given json node. 
if (propertyValue == null) {
    return;
if (isIntegerValue(propertyValue)) {
    node.set(propertyName, factory.numberNode(propertyValue.toBigInteger()));
} else {
    node.set(propertyName, factory.numberNode(propertyValue));
booleanbyteOverflow(BigDecimal value)
Checks for overflow when converting a BigDecimal to a byte. 
return value.compareTo(BIGDECIMAL_BYTE_MAX) > 0 || value.compareTo(BIGDECIMAL_BYTE_MIN) < 0 ? false : true;
BigDecimalcloneBigDecimal(BigDecimal bdOriginal)
Echtes Klonen von BigDecimals. 
if (bdOriginal == null) {
    return null;
} else {
    return bdOriginal.setScale(bdOriginal.scale());
JsonNumbercreateJsonNumber(BigDecimal d)
create Json Number 
return new JsonNumber() {
    @Override
    public boolean isIntegral() {
        return d.scale() == 0;
    @Override
    public int intValue() {
        return d.intValue();
...
StringcreateReconFileHeader(int totalCount, BigDecimal totalAmount)

BigDecimal x = new BigDecimal("1", mc);
for (int i = 0; i < ITER; i++) {
    x = x.subtract(
            x.pow(3, mc).subtract(b, mc).divide(new BigDecimal("3", mc).multiply(x.pow(2, mc), mc), mc),

if (decimal == null) {
    return null;
final BigDecimal bd = new BigDecimal(decimal);

    throw new IOException("Decimal " + bd + " has more then 12 digits of scale");
if (bd.precision() > 38) {
...
BigDecimalexp(BigDecimal power)
Raises e to the power of the input big decimal. 
int precision = power.precision();
MathContext context = new MathContext(precision, RoundingMode.HALF_DOWN);
return exp(power, context);
