is roughly as follows: Local now = OS. Time () Local pre = task. completed_time Local refresh = (15-8) * (60*60)--Subtraction8BecauseOS. Time ()The result is:UTCTime, while Beijing time isUTC + 8 Local pre_days = (pre-Refresh)/(24*60*60) Local now_days = (now-Refresh)/(24*60*60) If (now_days> pre_days) then --Refresh task End Very concise. The entire algorithm only needs one time function --OS. Time (). I thought this was done in this way, but after repeated tests, the tragedy occurred: the se

BC is the abbreviation of binary calculator. The arguments for the bc* function are the operands plus an optional [int scale], such as String Bcadd (String $left _operand, String $right _operand[, int $scale]), if scale does not provide , the default value of Bcscale is used. The large number is directly represented by a string of 0-9, and the result returns a string. Bcadd-adds two high precision numbersbccomp-compares two high-

Precision and query completion rate are two quantitative indicators of Information Retrieval Efficiency Evaluation. They can not only be used to evaluate the accuracy and comprehensiveness of each retrieval, it is also an important aspect of measuring the retrieval performance of the information retrieval system. Precision ratio (P) refers to the percentage of the number of relevant documents detected in th

Because JS multiplication and add and subtract operations sometimes have the problem of loss of precision, at the same time, two non-numeric addition will also appear the problem of type conversion, so specifically wrote a arithmetic JS not lost precision version to deal with JS arithmetic. /** * Exact addition * * @param {String | Number} Arg1 * @param {String | Number} arg2 * * @returns {number} arg1 +

Power of High Precision Time limit:500 ms Memory limit:10000 K Total submissions:120785 Accepted:29494 DescriptionIt is a very common problem to perform high-precision calculation on numbers with large numbers and high precision. For example, calculating national debt is a problem of this type. The problem you want to solve

T1: Number theory + high precision (water ~) According to the question, the bigger the number of division, the better (in the range of 0 ~ 9) So we only need to use high-precision division and then simulate it. // MARK: However, note that the special value 0-9 requires special determination. Because the output number of the question must be at least two digits, 1 should be added before the 0-9 output. if

The idea for this question is quite simple, mainly to make a high-precision ride, and then consider some details. The code is quite short, but it has been wrong for a long time... Let's talk about the ideas: This is to remove the decimal point when reading the data. Mark the decimal point location. Remove the decimal point and then perform high-precision multiplication. Remove the leading zero. Then calcula

Many concepts do not understand the internet. Take the basic concepts of "recall rate" and "accuracy rate" and look at the information on the Internet. When I use the information, I want to understand it in my mind, when someone else is ready to use it, you still have to think about it. I specially found some materials and sorted out these two concepts, hoping to be more proficient. Recall rate and accuracy are two important concepts and indicators in the design of search engines (or other retri

The trouble with this question is to followVertical formatOutput, and some detai

-bit... Here _ declspec (naked) is not required .. As mentioned above. The key is the rdtsc command (read time stamp counter) to obtain the high-precision timestamp of the CPU. You can also write as follows: _ Declspec (naked) unsigned _ int64 getcpucycle (void){_ ASM{_ ASM _ emit 0x0f_ ASM _ emit 0x31RET}} This is equivalent to the machine code that is directly pushed into the command. The original post said that rdtsc cannot be recognized in the
