Description

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

Method

BigDecimaltoBigDecimal(long seconds, int nanoseconds)
to Big Decimal 
if (nanoseconds == 0L) {
    if (seconds == 0L) { 
        return BigDecimal.ZERO.setScale(1);
    return BigDecimal.valueOf(seconds).setScale(9);
return new BigDecimal(toDecimal(seconds, nanoseconds));
BigDecimaltoBigDecimal(Number n)
Convert the given Number to a BigDecimal 
if (n instanceof BigDecimal) {
    return (BigDecimal) n;
if (n instanceof BigInteger) {
    return new BigDecimal((BigInteger) n);
return new BigDecimal(n.doubleValue());
BigDecimaltoBigDecimal(Number n)
Converts any number to a BigDecimal, suited for comparison and (monetary) arithmetic. 
if (n instanceof BigDecimal) {
    return (BigDecimal) n;
if (n instanceof Long) {
    return new BigDecimal((Long) n);
} else if (n instanceof Integer) {
    return new BigDecimal((Integer) n);
} else if (n instanceof Float) {
...
BigDecimaltoBigDecimal(Number n)
to Big Decimal 
BigDecimal bd;
if (n == null) {
    throw new IllegalArgumentException("Your number is null");
} else if (n instanceof BigDecimal) {
    bd = (BigDecimal) n;
} else if (n instanceof BigInteger) {
    bd = new BigDecimal((BigInteger) n);
} else if (n instanceof Short || n instanceof Long || n instanceof Integer) {
...
BigDecimaltoBigDecimal(Number n)
Converts a number into BigDecimal representation. 
if (n instanceof BigDecimal)
    return (BigDecimal) n;
return new BigDecimal(n.toString());
BigDecimaltoBigDecimal(Number num)
to Big Decimal 
try {
    return num instanceof BigDecimal ? (BigDecimal) num : new BigDecimal(num.toString());
} catch (NumberFormatException e) {
    throw new NumberFormatException("Can't parse this as BigDecimal number: " + num);
BigDecimaltoBigDecimal(Number number)
Converts (almost) any number to BigDecimal . 
if (number instanceof BigDecimal)
    return (BigDecimal) number;
return new BigDecimal(number.toString());
BigDecimaltoBigDecimal(Number number)
We should convert each number to java.math.BigDecimal to compare different number types: Byte, Short, Integer, Long, Float, Double, BigDecimal, etc 
if (number.getClass() == Integer.class || number.getClass() == Long.class
        || number.getClass() == Short.class || number.getClass() == Byte.class) {
    return BigDecimal.valueOf(number.longValue());
} else if (number.getClass() == Double.class || number.getClass() == Float.class) {
    return BigDecimal.valueOf(number.doubleValue());
} else if (number.getClass() == BigDecimal.class) {
    return (BigDecimal) number;
} else if (number.getClass() == BigInteger.class) {
...
BigDecimaltoBigDecimal(Number number)
Returns a java.math.BigDecimal representation of a given number.
If the class of a number isn't one of standard Java number classes, the conversion is made through number doubleValue() method call.
If a number is null then null is returned. 
if (number == null)
    return null;
if (number instanceof BigDecimal)
    return (BigDecimal) number;
if (number instanceof Long)
    return BigDecimal.valueOf((Long) number);
if (number instanceof Integer)
    return BigDecimal.valueOf((Integer) number);
...
BigDecimaltoBigDecimal(Number number)
Safely converts a number to a BigInteger. 
String type = number.getClass().getSimpleName();
BigDecimal parsed;
switch (type) {
case "Byte":
    Byte by = (Byte) number;
    parsed = new BigDecimal(by.doubleValue());
    break;
case "Short":
