Let's take a look at one of the following examples: Copy Code code as follows: Import Java.math.BigInteger; public class Bigproblem { public static void Main (string[] args) { BigInteger Fivethousand = new BigInteger ("5000");

These days to do a few words with a large number of questions, found that Java to larger number of operations is very convenient. It's very practical for acmer.1.valueOf (parament); To convert a parameter to a developed typesuch as int

First, let's take a look at the basic operation of Java large numbersⅠ Basic functions:1.valueOf (parament); To convert a parameter to a developed typesuch as int a=3;BigInteger b=biginteger.valueof (a);Then b=3;String s= "12345";BigInteger

The Java.math.BigDecimal class provides arithmetic, scale operations, rounding, comparison, hashing algorithms, and format conversion operations.The ToString () method provides a canonical representation of the BigDecimal. It gives the user full

Large numerical problems:If the basic integers (for example: int, long) and the precision of the floating-point number are not sufficient for the dog, then it is possible to use the two classes in the Java.math package BigInteger (integers of

When we meet long does not need to consider this bininteger, because this is as long as you have enough memory, you can enter a large number, with this processing of high-precision problems, it is very easy, for me this just learn Java new, long
