rint()

Example

Round numbers to their nearest integers.

System.out.println(Math.rint(0.5));
System.out.println(Math.rint(1.5));
System.out.println(Math.rint(5));
System.out.println(Math.rint(5.1));
System.out.println(Math.rint(–5.1));
System.out.println(Math.rint(–5.9));

Definition and Usage

The rint() method in Java rounds a number to the nearest integer. In cases where there are two integers equally close to the number, the even integer is returned.

Note: This method is similar to round(), with key differences:

round() returns long or int data types, while rint() returns a double.
When the decimal part of the number is exactly 0.5, rint() returns the nearest even integer, whereas round() returns the higher of the two nearest integers.

Syntax

public static double rint(double number)

Parameter Values

Parameter	Description
number	Please provide a number to be rounded.
