The floor function returns the largest whole number that is less than or equal to the input. This method only takes and returns double values. Take a look at the example below.

FloorMethodExample.java

package exlcode;
public class FloorMethodExample {
// Returns largest integer that is less than or equal to the argument
public static double exampleVariableOne = Math.floor(10.4);
public static double exampleVariableTwo = Math.floor(-20.4);
public static void main(String[] args) {
System.out.println(exampleVariableOne);
System.out.println(exampleVariableTwo);
}
}

As the nearest whole number that is less than or equal to 10.4 is 10, 10.0 is printed. Similarly, since the closest whole number that is less than or equal to -20.4 is -21, -21.0 is printed. Notice that even if we input a non-decimal number into the floor function, a double is returned. Since data precision is not hindered when you convert from an int data type to a double, Java will do it without throwing any errors. The floor function's primary use is rounding, all ready for you to use while coding.
