intin Java intis a primitive data type that is allocated 4 bytes of memory by most systems. It is used to store integer values, and its operations are faster than those of doubles. See the code below. publicclassintOperation{publicstaticvoidmain(String[]args){inta=20;intb=3;intc=a+b;...

* {@codeBigDecimal} objects equal only if they are equal in * value and scale (thus 2.0 is not equal to 2.00 when compared by * this method). * 该方法认为两个BigDecimal对象只有在值和比例相等时才相等,所以当使用该方法比较2.0与2.00时,二者不相等。
Double是Java中的一个包装类,用于表示双精度浮点数。它提供了一些方法来操作和处理双精度浮点数。 要使用原始double值初始化Double对象,可以使用Double类的构造方法。Double类提供了多个构造方法,其中一个接受一个double参数,用于将原始double值转换为Double对象。示例代码如下: 代码语言:java 复制 double originalValue =...
haseCode被重写了 public static int hashCode(double value) {long bits = doubleToLongBits(value);return (int)(bits ^ (bits >>> 32));} doubleToLongBits:很多方法中用到了这个方法,理解为将double转换为64位的long即可 根据IEEE 754浮点“双格式”位布局返回指定浮点值的表示。
1.2329999999999999Java中的简单浮点数类型float和double不能够进行运算。不光是Java,在其它很多编程语言中也有这样的问题。在大多数情况下,计算的结果是准确的,但是多试几次(可以做一个循环)就可以试出类似上面的错误。现在终于理解为什么要有BCD码了。 这个问题相当严重,如果你有9.999999999999元,你的计算机是不会认为你...
