Java floor() method with Examples
The java.lang.Math.floor() returns the double value that is less than or equal to the argument and is equal to the nearest mathematical integer. Note:
- If the argument is Integer, then the result is Integer.
- If the argument is NaN or an infinity or positive zero or negative zero, then the result is the same as the argument.
public static double floor(double a) a : the argument whose floor value is to be determined Returns : This method returns the double value that is less than or equal to the argument and is equal to the nearest mathematical integer.
Example 01:To show working of java.lang.Math.floor() method.
java
import java.lang.Math;
class Gfg {
public static void main(String args[])
{
double a = 4.3 ;
double b = 1.0 / 0 ;
double c = 0.0 ;
double d = - 0.0 ;
double e = - 2.3 ;
System.out.println(Math.floor(a));
System.out.println(Math.floor(b));
System.out.println(Math.floor(c));
System.out.println(Math.floor(d));
System.out.println(Math.floor(e));
}
}
|
Output:
4.0
Infinity
0.0
-0.0
-3.0
Example 02:To show the working of floor() with a positive double value.
Java
import java.io.*;
class GFG {
public static void main(String[] args)
{
double number = 3.5 ;
double result = Math.floor(number);
System.out.println(result);
}
}

Output :
3.0
