The **`floor()` function** returns the largest double value that is less than or equal to a specific number.

Figure 1, below, shows the mathematical representation of the `floor()` function.

# Syntax
```java
double floor(number num)
```
# Parameter
This function requires a number as a parameter.
> The number can be `int`, `float`, `double`, or `long`.

# Return Value
`floor()` returns the largest double value that is less than or equal to a specific number.

# Code


class JAVA {
    public static void main( String args[] ) {
        //integer
        System.out.println("Math.floor(2):");
        System.out.println(Math.floor(2));

        //positive double value
        System.out.println("Math.floor(2.56):");
        System.out.println(Math.floor(2.56));

        //negative double value
        System.out.println("Math.floor(-2.36):");
        System.out.println(Math.floor(-2.36));
    }
}
