Description

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

Method

ObjecttoObject(BigDecimal value)
to Object 
return value;
BigDecimaltoPercent(final BigDecimal decimalValue, final MathContext mathCntext)
to Percent 
return convertNullToZero(decimalValue).divide(ONE_HUNDRED, mathCntext);
StringtoScientificNotation(BigDecimal bd)
Formats a BigDecimal value to a string in scientific notation For example
  • A value of 0.00001234 would be formated as 1.234E-5
  • A value of 100000.00 would be formated as 1.00E5
  • A value of 100 (scale zero) would be formated as 1E2

    • If bd has a precision higher than 20, this method will truncate the output string to have a precision of 20 (no rounding will be done, just a truncate). 
    final int truncateAt = 20;
String unscaled = bd.unscaledValue().toString();
if (bd.signum() < 0) {
    unscaled = unscaled.substring(1);
int len = unscaled.length();
int scale = bd.scale();
int e = len - scale - 1;

BigDecimaltoSimpleBigDecimal(Object num)
to Simple Big Decimal 
try {
    return num != null ? new BigDecimal(num.toString()) : null;
} catch (Exception ignored) {
return null;
StringtoString(BigDecimal num)
to String 
if (num == null) {
    return "0";
} else {
    return num.setScale(2).toString();
StringtoString(BigDecimal value, int numberDecimalPlaces)
to String 
String newStr = null;
if (value != null) {
    try {
        newStr = String.format("%." + numberDecimalPlaces + "f", value);
        int posCorte = newStr.lastIndexOf(".");
        if (posCorte >= 0) {
            String decimal = newStr.substring(posCorte + 1);
            if (decimal.length() > numberDecimalPlaces) {
...
StringtoString(final BigDecimal dec)
to String 
return dec.toPlainString();
StringtoUnsignedString(BigDecimal bigDecimal, int shift)
to Unsigned String 
BigDecimal divisor = new BigDecimal(shift);
Deque<Character> numberDeque = new ArrayDeque<Character>();
do {
    BigDecimal[] ba = bigDecimal.divideAndRemainder(divisor);
    bigDecimal = ba[0];
    numberDeque.addFirst(digits[ba[1].intValue()]);
} while (bigDecimal.compareTo(BigDecimal.ZERO) > 0);
StringBuilder builder = new StringBuilder();
