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 :To show working of java.lang.Math.floor() method.
// Java program to demonstrate working// of java.lang.Math.floor() methodimport java.lang.Math; class Gfg { // driver code 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)); // Input Infinity, Output Infinity System.out.println(Math.floor(b)); // Input Positive Zero, Output Positive Zero System.out.println(Math.floor(c)); // Input Negative Zero, Output Negative Zero System.out.println(Math.floor(d)); // Input -2.3, Output -3.0 // Nearest Integer(-3.0) < less than (-2.3) System.out.println(Math.floor(e)); }} |
Output:
4.0 Infinity 0.0 -0.0 -3.0
