. Because it is a positive number, the index bit is 13 + 127 = 140 (127 is the single-precision floating point offset value, to indicate the number of digits with only decimals), the valid bit is 1000000111001.When calculating with (-1) ^ s * 1.f * 2 ^ (e-127), the result is 1*1.1000000111001*2 ^ (140-127 = 13 ), same as what we just saidFor example, if decimal 0.125 is converted to binary decimal 0.001, it

scheduled to execute by the kernel.Executing: In executionUninterruptible: Non-disruptive sleep state, which means that the kernel will not be able to execute the process to the CPU at this time, such as the process going to the IO request data, but not ready at this time.Interruptible: interruptible sleep state, similar to ready, can be executed by kernel schedulerZombie: Zombie State, the process is over, but the memory cannot be freed, such as because the task structure of the process that a

consumption slow a bit of user perception, electrical signals and biological signals operating speed gap is huge. Although the kernel allocates as many time slices as possible to the IO-consuming process, the IO consumption process often sleeps, giving it no time slices at all. Is that reasonable?So how does the kernel implement this eccentricity? This is achieved by dynamically adjusting the priority of the process and assigning different lengths of CPU time. First say how the kernel determine
