Java Math floor() Method
Example
Round numbers down to the nearest integer:
System.out.println(Math.floor(0.60));
System.out.println(Math.floor(0.40));
System.out.println(Math.floor(5));
System.out.println(Math.floor(5.1));
System.out.println(Math.floor(-5.1));
System.out.println(Math.floor(-5.9));
Definition and Usage
The floor() method rounds a number DOWN to
the nearest integer.
Tip: To round a number UP to the nearest integer, look at the ceil() method.
Tip: To round a number to the nearest integer in either direction, look at the round() method.
Note: For positive numbers the floor() method just removes the decimal part, but for negative numbers the integer part of the number will be changed if the number has a decimal part. If you only want to remove the decimal part, you can type cast the number as an integer.
