(1)三种变量修饰符 val 定义immutable variable(常量); var 定义 mutable variable(变量); lazy val(只有当该变量首次被使用的时候才会取值) ; 可以不显示指定变量类型,因为Scala会自动进行类型推导。 2、Scala的类型体系 (1)常用类型:Byte、Char、Short、Int、Long、Float、Double和Boolean。 与Java不同的是,这些...

We could use the template in integer number fields, floating point number fields or some other number fields without rewrite the source code. The Linbox package has been integrated into parallel GNFS package. For integer factorization process, we use GNFS package first, to select parameters, set...
Note that you can't use instanceof or cast ((IntegerValue) thisValue) to check type of a value because type of a mutable value is variable.[中]将值作为IntegerValue返回。否则抛出MessageTypeCastException。请注意,不能使用instanceof或强制转换((IntegerValue) thisValue)来检查值的类型,因为可变值的...
