multi precision integer

because the computer operation is a modulo operation, the representation of the data range is limited, such as int (c + + in the same int and long) expression range ( -2^31~2^31-1), unsigned long (unsigned integer) is (0~2^32-1), are about billions

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

The PI program on vier gourdon is a good start for computing, piclassic. I downloaded the C program and compiled it with/O2. I found that it is still a little faster than I did without changing my mind. Of course it cannot be compared with the above
