precision in c programming

How to obtain the time in C language? How accurate? 1 use time_t time (time_t * timer) to be accurate to seconds 2 using clock_t clock (), the CPU time is accurate to 1/clocks_per_sec. 3. Calculate the time difference using double difftime (time_t

In a recent project, a high-precision real-time clock is required under VxWorks, with a precision of 1ms and an overflow time of more than 5 hours. The VxWorks provides a system clock that starts counting after the operating system starts, with a

This article is mainly on the JavaScript to avoid the error of digital calculation method is introduced, the need for friends can come to the reference, I hope to help you What if I ask you 0.1 + 0.2 equals a few? You may send me a supercilious eye,

If I ask you 0.1 + 0.2 equals how many? You may send me a supercilious eye, 0.1 + 0.2 = 0.3 Ah, that still ask? Even the kindergarten children will answer such a childish question. But you know, the same problem is in the programming language, maybe
