java的BigInteger如何转为int java中biginteger怎么用 在java中,有很多基本数据类型我们可以直接使用,比如用于表示浮点型的float、double,用于表示字符型的char,用于表示整型的int、short、long等。但是,拿整数来说,如果我们想要表示一个非常大的整数,比如说超过64位,那么能表示数字最大的long也无法存取这样的数字时,我们...

System.out.println(b1.multiply(b1).longValueExact());//java.lang.ArithmeticException: BigInteger out of long range} } 在使用longValueExact()方法时,如果超出了long型的范围,会抛出ArithmeticException。 BigInteger和Integer、long一样,也是不可变类,并且也继承自Number类, ...
BigInteger是不可变的任意精度的整数。所有操作中,都以二进制补码形式表示BigInteger(如 Java 的基本整数类型)。BigInteger提供所有 Java 的基本整数操作符的对应物,并提供java.lang.Math的所有相关方法。另外,BigInteger还提供以下运算:模算术、GCD 计算、质数测试、素数生成、位操作以及一些其他操作。

Object.equals(java.lang.Object) System.identityHashCode(java.lang.Object)toString public String toString(int radix) Returns the String representation of this BigInteger in the given radix. If the radix is outside the range from Character.MIN_RADIX to Character.MAX_RADIX inclusive, it will default...
The range of probable prime values is limited and may be less than the full supported positive range of BigInteger. The range must be at least 1 to 2500000000. Added in 1.1. Java documentation for java.math.BigInteger.Portions of this
