This article mainly introducesLinuxLow PrecisionTimeFunction, and related functions with a timeout mechanism.TimerIt also gives a brief introduction. In linux, the most accurate time interface is gettimeofday. It returns a timeval structure with the precision of us (10-6 seconds). In most cases, this precision is enough. However, sometimes we need to explore the time calls provided by Linux for us for highe

Based on the previous post, the modification and subtraction operations are suitable for high-precision floating point computing. Because the subtraction method is more difficult than the addition method, more considerations are required, and the code may be lacking. Operation description: 1. The subtraction function remains unchanged, including the size function used to determine the subtrahend and subtravers. 2. added two functions: the decimal poin

Introduction This article describes how to use C # For a high-precision timer. Sometimes we need a timer with higher accuracy and sleep, but the sleep is not accurate. So I had to customize it myself. Background In general systems, sleep (1) is equivalent to 15.625 ms (1/64 seconds), that is, sleep (15) is the same as sleep.

Remove spaces at the beginning and end, check whether the string contains Chinese characters, open a new window, verify the IP address, normalize the floating point number to the specified precision, and determine whether the provided string is empty, determines whether the provided string is an integer, whether the input character is capital or a letter, whether the input character is 0-9 numeric, whether the provided string contains only numeric cha

First, let's look at a special example.In the above expression, we can calculate the mental arithmetic is 0, why is a close to 0 of the number?This will start from the small number of precision.1. Generation of decimalsThis type of decimal is typically created by an expression or by referencing other module operations, rather than by assigning values to variables.2. Decimal objectsWe can use decimal objects to control the fractional output3. Using the

The traffic policeman recorded the position of the old driver at nn a point in time, but the time position. It is known that the old driver departs from position 0, and the recorded time points are integers, asking nn for the minimum time required to go through the first position.Puzzle: The last part of the journey must be 1 seconds, only

Recently, I am using VB.net for an infinite classification. I suddenly found a precision problem with VB.net. Now I am sending it to my garden to see if you have any ideas or solutions. Code As follows: String . Format ( " {0 :####################} " , 2 ^ 63 - 1 ) The above is the 63 power of 2 minus the value of 1.Output result: 9223372036854780000If the format is not used, the result is: 922337204255478e + 18.T

For two numbers, the example of the first number is 10 ^ 100, the second number is 10 ^ 6, and the first number is the product of the two prime numbers, ask if the number that does not exceed the second number is the factor of the first tree. Idea: 10 ^ 6 contains only 7 W + prime numbers. You only need to judge one by one whether it can be divisible. Then the prime number of this question must be linear, otherwise it will be T. In addition, I pressed four digits at the beginning of high
