The double type and float type are primarily designed for use in scientific and engineering calculations and are used for binary floating-point calculations. For the general calculation is usually inaccurate results, so for the ordinary floating-point addition and subtraction, the solution needs to use Int,long,bigdecimal to calculate. 1. Calculate the problem?The calculation results are as follows:Obviously the result is not what we need. The result we need is: 0.88So, our program should write

Time-class functions are often used in the daily development process, where the UTC time of 1970 is more commonly used, but there are no functions that are directly accurate to the delicate level under Windows. This article provides a way to solve this type of demand problem.

Apple, the German is called Di Li, the American is called the Irish Yambean, the Russian is called the Dutch potato. If we sell potatoes, can we classify the users according to different terms? 1. When we use the potato as the key word, what kind of customer group are we? Do they like to eat potatoes, do we need to spend a lot of energy to do optimization? Can you assign them to that potential customer group? 2. When we use potato as the key word, what kind of customer group are we? What are
