The two classes of Java, biginteger and bigdecimal, represent the big integer class and the big floating point class respectively. Theoretically, they can represent an infinite number.
Biginteger:

It is very troublesome to process large numbers in C or C ++, but there are two classes in JAVA: BigInteger and BigDecimal, which respectively represent the big integer class and the big floating point class, objects of the two classes can indicate the maximum range is unclear. Theoretically, they can represent a large number of wireless devices, as long as the computer memory is large enough.
Both classes

BigInteger and BigDecimal are existing classes in the java. math package. The former represents an integer, and the latter represents a floating point.
Why use big numbers?
1) BigInteger: an integer of any precision is supported. It can accurately represent an integer of any size without any information loss During computation.
2)

parameterPublic BigInteger remainder (BigInteger val) returns the remainder of the current large integer object and the large integer object specified by the parameter.public int CompareTo (BigInteger val) Returns the result of the comparison of the current large integer object with the large integer object specified by the parameter, which is 1,-1, 0, respectiv

When we are dealing with very large data, the usual data types are not enough to indicate that in Java there are two classes BigInteger and BigDecimal representing the large integer class and the large floating-point number class, the two classes in theory as long as the computer memory is large enough Can represent a large number of wireless. They are all in the java.math.* package and can be viewed in the

In java, there are many things that are easy to ignore. Today, I saw a java puzzle on the Internet. The Code is as follows:[Java]BigInteger five = new BigInteger ("5 ");BigInteger four = new B

In Java there are two classes BigInteger and bigdecimal that represent immutable arbitrary-precision integers and immutable signed arbitrary-precision decimal numbers (floating-point numbers). It is mainly used in high precision calculation. These two classes make large numbers in Java, high-precision operations become very simple, as for the two classes of objec

In Java, there are many things that are easy to ignore. Today, I saw a Java puzzle on the Internet. The Code is as follows:
BigInteger five = new BigInteger("5");BigInteger four = new BigInteger("4");

You can delete the number of 2 to k and add the product of the deleted number to the original array until only one number is left to calculate the maximum and minimum values. difference
The smaller the number of values selected, the less the number of values selected. The larger the result is, the larger the result is. Because thi

data, I can still easily solve it in Java, after all, Java has already encapsulated the processing of big data in BigInteger.The following is the basic use of BigInteger, that is, the construction method and the four mixed operation:public static void Bigintegertest () {BigInteger num1 = new

The BigInteger class is Java in order to handle large number two specialized classes, can handle very large numbers (theoretically infinitely large), and can achieve large numbers similar to int all mathematical operations. For the algorithm problem, no longer afraid of the operation beyond the scope of int!At the same time, the class dealing with large floating-point numbers is BigDecimal.BigInteger mainly

Big Data OperationsBigIntegerThe long type in Java is the largest integer type, and how to represent data that is longer than long. In the world of Java, integers longer than long can no longer be called integers, and they are encapsulated as BigInteger objects. In the BigInteger class, Implementing arithmetic is imple

a BigInteger classWhen we have to deal with a very large number, we must not be able to use int and long. Of course, we can use string to receive large numbers, and then split the way to calculate, but this way is cumbersome. Therefore, in order to solve this problem in Java, the BigInteger class is provided. The BigInteger
