异常信息“exception in thread "main" java.lang.arithmeticexception: rounding necessary”表明,在Java程序的主线程中发生了一个算术异常,具体原因是需要进行舍入操作但未提供舍入规则。 2. java.lang.ArithmeticException异常的具体含义和触发条件 java.lang.ArithmeticException是Java中的一个运行时异常,当数学运算发生...
JAVA程序异常:java.lang.ArithmeticException: Non-terminating decimal expansion; no exact representable decimal result。 发现报错的语句是: 1 foo.divide(bar)); 原来JAVA中如果用BigDecimal做除法的时候一定要在divide方法中传递第二个参数,定义精确到小数点后几位,否则在不整除的情况下,结果是无限循环小数时,就会...

To achieve better precision, Java provides the BigDecimal class. Unlike float and double, which use approximation, this class is able to represent the exact value of a decimal number. However, it comes with a drawback: BigDecimal is treated as an object and requires additional CPU and memory ...
Long story short, I've created a class called BigInt purely written in Java, which is pretty neat and outperforms BigInteger. There are most likely (many) bugs, but since it's pretty basic at the moment, it'll be a great opportunity for the Codeforces community to learn how to do ...
}}//情况2class Demo{public static void main(String[] args){System.out.println(5%0);}}Exception in thread "main" java.lang.ArithmeticException: / by zero 这段异常就是上面代码报错的异常，任何数除0或模0都是一个不成立的运算，所以你可用检查下你的代码，应该是出现了这种错误代码。除...
