clock_t difference in 6 decimal positions

Question

I use this code for measuring computing time of my C program:

clock_t start = clock() ;
do_some_work() ;
clock_t end = clock() ;
double elapsed_time = (end-start)/(double)CLOCKS_PER_SEC ;

Problem is, that this double elapsed_time returns only number with 2 decimal positions, like 1,78 seconds, but I want to enlarge it to 6 decimal positions. Is there any way how to do it?

Thanks

Please post your code where you print the value, you've most likely just have a format problem. — DarkDust, Apr 14 '11 at 10:35
