importjava.math.BigDecimal;/*java2s.com*/publicclassMain {publicstaticvoidmain(String[] args) { BigDecimal first =newBigDecimal(-1f); BigDecimal second =newBigDecimal(10f); System.out.println(first.compareTo(second)); } } The output:
“0.0”.compareTo(BigDecimal.ZERO) “0.00”.compareTo(BigDecimal.ZERO) Here’s an example: import java.math.BigDecimal; public class BigDecimalTest { public static void main(String[] args) { BigDecimal bd = new BigDecimal(0); System.out.println(new BigDecimal("0").compareTo(BigDecimal.ZERO)...

Oracle, MS SQL Server, and Informix all use this form of encoding, as do decimal arithmetic libraries, including decNumber for C, bignum for Perl 6, Decimal in Python 2.4, EDA for Eiffel, ArciMath and IBM's BigDecimal classes for Java, ADAR for Ada, and the X/Open ISAM decimal type....

equals is in red so guessing it has to be warped (Integer) looks like it can only compare objects, just think there must be a way of compare two primitive data types in java but can't work it out been going over all the basics in java and just can't work this one out thanks...
Change the last statement of my BigDecimalTest class which I posted a few minutes back to read like this, and try again. ? 1 2 out.printf("%s compared to [000]%s = %d, equals %b%n", bg2, bg1, bg2.compareTo(bg1), bg2.equals(bg1)); Ilja Preuss author Posts: 14112 posted ...

Hello guys, After Java 8 it has become a lot easier to work with Comparator and Comparable classes in Java. You can implement aComparatorusing lambda expression because it is a SAM type interface. It has just one abstract methodcompare()which means you can pass alambda expressionwhere aCompar...
For this reason, two instances ofBigDecimalshouldn’t be compared using theequals()method, but instead thecompareTo()method should be used, because it compares the numerical values (x= 1;y= 1.0) represented by the two instances ofBigDecimal. Here’s an example: ...
