What kind of number is it? If it's a float, then you can say:

myFloat = roundf(1000 * myFloat) / 1000.0;

If it's a double, use the round() function instead.

Found this on SO, that shows examples of floor(), or ceil() http://stackoverflow.com/questions/1343890/rounding-number-to-2-decimal-places-in-c/1344261#1344261 – markhunte Mar 18 '11 at 11:10
