JAVA超大数的运算(BigInteger类) 如果要进行非常大的数计算或者高精度浮点数的计算,可以使用java.math包中的BigInteger类。它们都是不可变的。 注意是任意大小与任意精度的数。 在代码开头一定要 import java.math.*; Java 代码语言:txt import java.math.*; public class javaLang { public static void main(Str...

Java的大数分为两种,一种是整数类型的,一种是小数类型的BigDecimal,一种是整数类型的BigInteger 本篇文章就讲一下Java中BigInteger的使用 提交代码 在提交Java代码的时候,不能含有导入的包package的名字 在新建Java类的过程中,一般情况下要将类命名为Main 否则再提交代码之后会报错 ...
Parameters: radix- radix of the String representation. Returns: String representation of this BigInteger in the given radix. See Also: Integer.toString(int, int),Character.forDigit(int, int),BigInteger(java.lang.String, int)
