Use the round() function in the C99 standard library.
Example:
#include<math.h>
#include<assert.h>
double x = 0.1234567;
assert ((round (x * 10) / 10) == 0.10);
assert ((round (x * 100) / 100) == 0.120);
assert ((round (x * 1000) / 1000) == 0.1230);
assert ((round (x * 10000) / 10000) == 0.12350);
assert ((round (x * 100000) / 100000) == 0.123460);
assert ((round (x * 1000000) / 1000000) == 0.1234570);
assert ((round (x * 10000000) / 10000000) == 0.12345670);
