From the javadocs for java.lang.StrictMath:
round
public static long round(double a)
Returns the closest long to the argument. The result is rounded to
an integer by adding 1/2, taking the floor of the result, and casting
the result to type long. In other words, the result is equal to the
value of the expression:
(long)Math.floor(a + 0.5d)
Give you any ideas?
ps. There's also a method by the same name which takes a float argument
and returns an int.
