Method:

public static double rint(double a)

Returns the double value that is closest in value to the argument and is equal to a mathematical integer. If two double values that are mathematical integers are equally close, the result is the integer value that is even.


Examples


package com.logicbig.example.math;

public class RintExample {

    public static void main(String... args) {
        value(5.475);
        value(8.91);
        value(2.5);
        value(3.5);
        value(0.00);
        value(Double.POSITIVE_INFINITY);
    }

    private static void value(double a) {
        double result = Math.rint(a);
        System.out.printf("Math.rint(%s) = %.2f%n", a, result);
    }

}

Output

Math.rint(5.475) = 5.00
Math.rint(8.91) = 9.00
Math.rint(2.5) = 2.00
Math.rint(3.5) = 4.00
Math.rint(0.0) = 0.00
Math.rint(Infinity) = Infinity
