BigDecimal compareTo in Java - Learn how to use the BigDecimal compareTo method in Java to compare two BigDecimal values effectively.
In this article we show how to perform high-precision calculations in Java with BigDecimal. BigDecimalrepresents an immutable, arbitrary-precision signed decimal number. It is used for high-precision arithmetic.BigDecimalprovides operations for arithmetic, scale manipulation, rounding, comparison, hashing, ...
在Java中,我们可以使用BigDecimal的compareTo()方法来比较查询中的BigDecimal值是否在某个范围内。compareTo()方法返回一个int值,用于表示比较结果。 下面是一个比较BigDecimal值是否在某个范围内的示例代码: 代码语言:txt 复制 import java.math.BigDecimal; public class BigDecimalComparison { public static void...
* {@code BigDecimal}. Two {@code BigDecimal} objects that are * equal in value but have a different scale (like 2.0 and 2.00) * are considered equal by this method. This method is provided * in preference to individual methods for each of the six boolean * comparison operators ({@liter...
Exception in thread "main" java.lang.IllegalArgumentException: Comparison method violates its general contract! Google了这个错误,是由于Java 7内置的新排序算法导致的。这才猛然想起产品的编译环境最近升级到了Java 7。 2. 结论 在Java 6中Arrays.sort()和Collections.sort()使用的是MergeSort,而在Java 7中,...
Just like the otherNumberclasses (Integer,Long,Double,etc.),BigDecimalprovides operations for arithmetic and comparison operations. It also provides operations for scale manipulation, rounding, and format conversion. It doesn’t overload the the arithmetic (+, -, /, *) or logical (>. < etc) ...
BigDecimal has a safer version ofintValue()–intValueExact().This method would throwArithmeticExceptionon any overflow in the decimal part: @ParameterizedTest @ValueSource(longs = {Long.MAX_VALUE, Long.MAX_VALUE - 1, Long.MAX_VALUE - 2, ...
The suggested idiom for performing these comparisons is: (x.compareTo(y) <op> 0), where <op> is one of the six comparison operators. Specified by: compareTo in interface Comparable<BigDecimal> Parameters: val - BigDecimal to which this BigDecimal is to be compared. Returns: -1, 0, or ...
So far in this article, we have learned BigDecimal and its comparison in Java. We have learned how to compare if a BigDecimal value is greater than zero or not. In primitive data types, we can do this comparison with the help of relational operators, while in BigDecimal, we have to use...
