Let's look at two questions: 0.1 + 0.2 = 0.3; False9999999999999999 = 10000000000000000; True The first problem is the problem of decimal precision, which has been discussed in many blogs in the industry. The second problem is that last year, the

In order to solve the problem that the Java basic data type will overflow and be computationally inaccurate during operation. Java provides two classes of BigInteger and BigDecimal, specifically for high-precision operations. Anything that can be

Problem description In the project using Java to do floating-point calculation, found that for 4.015*100 such a calculation, the result is not expected to 401.5, but 401.49999999999994. Such a long number of digits is unfriendly to the display.

The simple floating-point number types in Java float and double are not capable of operation. It's not just Java, it's also a problem in many other programming languages.What will we see if we compile and run the following program?public class Test {
