The java.lang.Math class has static methods: public static int round(float x) public static long round(double x) which round to the nearest integer/long as appropriate. Alternatively, you can do it "by hand" by adding 0.5 and taking the floor...it's what Math.round() does for you. Probably best to use the library method anyway, as it's already tested and known to work...and people reading your code will recognise it more easily. See that API documentation for Math: http://download.oracle.com/javase/6/docs/api/java/lang/Math.html Good luck, Stephen -- To post to this group, send email to [email protected] To unsubscribe from this group, send email to [email protected] For more options, visit this group at http://groups.google.com/group/javaprogrammingwithpassion?hl=en
