Question

I am looking for a Java function that rounds up or down, but normally, like 3.2 to 3, and 3.6 to 4. There are a bunch of answers, but all of them either rounding up exclusively or rounding down exclusively. If there is not one then I guess I will have to create it, but just wanted to see if anyone else has ever wanted the same and found one. Thanks in advance!

Answer 1

Math.round():

public static int round(float a)

Returns the closest int 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 int. In other words, the result is equal to the
value of the expression:

(int)Math.floor(a + 0.5f)

Parameters:

• a – a floating-point value to be rounded to an integer.

Returns:

the value of the argument rounded to the nearest int value.
