1. Concurrent Programming Concepts of Atomic An operation cannot be split again, that is, an operation or multiple operations are either fully executed and the process of execution is not interrupted by any factor or executed. A classic example is

The Turbo code skillfully constructs the long code with pseudo random character by the parallel cascade of two simple component codes through pseudo random interleaving, and realizes pseudo random decoding by multiple iterations between two

In JavaScript, when you use decimal to perform a subtraction operation, you will find that the resulting results are sometimes followed by a long fractional fraction, which complicates the operation and affects the results of the calculation. The
