First, with JS calculation12.32 * 7 How much is the result? Answer: 86.24000000000001
Why is there such a problem? How to solve?JS in processing decimal multiplication and division of the time there is a bug, the solution can be: The decimal into an integer to deal with.The above calculation can be read as follows:12.32 * 100 * 7/100The result is: 86.24, correct.
In addition, calculate again:8.80 * 100 * 12/100Results: 105.60000000000002A similar pr
The processing of 1.1 VDSP to float division operation
Under VDSP, you can easily use:
float fdiv(float x, float y) { float r = x / y; return r; }
To complete the floating-point division operation, the compiler automatically converts the multiplication inside to the ___float32_div function call, which is implemented in Libdsp/fpdiv.asm, which describes the use of the function at the beginning of the file

The Problem
After centuries of hostilities and skirmishes between the Four nations living into the land generally known as Nlogonia, and Years of negotiations involving diplomats, politicians and the armed forces of all interested, with parties by UN, NATO, G7 and SBC, it was in last agree
Yesterday, I saw a news-Yahoo canceled the QA team, the engineer must be responsible for the code quality, and use continuous integration instead of QA. At the same time, also heard netizens said, "Listen to Microsoft to do Database Operations engineer Introduction, they are also the operation and maintenance engineers and test engineers canceled, by the development of all completed." Everyone is an all-stack engineer. " So, I quoted a few years ago wrote an article "Do we need full-time QA?" ,

It was expected to have functions such as div_fr1x16 to achieve Fract16 division, but unfortunately VDSP did not provide such a function directly, it is rather embarrassing, it is estimated that the CPU does not directly provide Fract division. However, the VDSP document provides an example of division:

Divide and conquer the idea of the law: The original problem is divided into several smaller but similar to the original problem of sub-problem, the recursive solution of these sub-problems, and then merge the solutions of these sub-problems to establish the solution of the original problem.The divide-and-conquer approach is followed in three steps for each level of recursion:(1) decomposition of the original problem is a number of sub-problems, these sub-problems are small instances of the orig
median, and the right subtree is greater than or equal to the median. Of course, this is for the only time the median value of the practice, one will say how many median value should be handled.
The second step: for each of the subgroups, we use the first step to divide, until the left and right intervals are equal, that is, to terminate the recursive conditions.
Step three: When we put a number into the Zoozi tree, we also have to count how many numbers in the interval [left,right] have entere
