↳java.lang.Double Double类将原始类型double的值包装在对象中。类型为Double的对象包含类型为double的单个字段。 另外,该类提供了几种将double转换为String和String转换为double,以及处理double时有用的其他常量和方法。 Summary Constants intBYTES 用于表示double值的字节数。
In contrast,adoubleis a 64-bit double-precision floating-point type, requiring eight bytes of memory. While it demands more storage, this larger size allows it to represent values with higher precision and a broader range, making it indispensable for tasks involving complex calculations or large ...
