Why is front-end numerical precision lost? (BigInt solution)

I believe that all front-end partners will inevitably be involved in using JavaScript to process numerical values in their daily work, such as numeric calculations, retaining specified decimal places, interface return values that are too large, etc. These operations are all possible. As a result, originally normal values do behave abnormally in JavaScript (ie, precision […]

Math class, BigInteger, BigDecimal, Date, Calendar, SimpleDateFormat, LocalDate, Period, Duration, System and Arrays class

Math class 1. Overview: ? Math tools 2.Features: ? a. Construct private ? b. Methods are all static 3.Use: ? Math. Directly call the class name 4.Math class method static int abs(int a) -> Find the absolute value of the parameter static double ceil(double a) -> round up static double floor(double a) -> round down […]

GMP library usage and BigInteger and BigDecimal in java

1. GMP introduction and installation The full name of GMP library is GNU Multiple Precision Arithmetic Library, which is the GNU high-precision arithmetic operation library. In the software implementation of various encryption algorithms in the field of network security technology, there is always a common topic of how to realize large number calculations on ordinary […]

3.2. Mathematics (Math, BigInteger, BigDecimal)

1. Math class The Math class provides some basic mathematical functions, such as square root, absolute value, trigonometric functions, etc. It is a final class, and all methods are static, so there is no need to create an object, just use the class name to call the method directly. The following are some common methods […]

java — Math, BigInteger, BigDecimal classes and wrapper classes for basic types, regular expressions

Math The java.lang.Math class contains methods for performing basic mathematical operations, such as elementary exponentials, logarithms, square roots, and trigonometric functions. All methods of a tool class like this are static methods, and no objects are created, so they are very simple to call. Math.PI // static constant public static final double PI = 3.14159265358979323846; […]

Use of BigInteger/BigDecima

Large numbers When the numbers processed in our programming are relatively large or the precision is very high, at this time long/double is not enough, we can use BigInteger/BigDecimal to process (specially used in financial software) BigInteger/BigDecimal is not a basic data type, but a reference data type The numbers of BigDecimal/BigInteger are objects, and […]

Java large number operations (BigInteger class and BigDecimal class)

Classes for large number operations are provided in Java, namely java.math.BigInteger class and java.math.BigDecimal class. These two classes are used for high-precision calculations, among which the BigInteger class is a processing class for large integer numbers, and the BigDecimal class is a processing class for large and small numbers. BigInteger class If you want to […]
