Java Math nextDown() Method
Example
Find the next floating point number below different numbers:
System.out.println(Math.nextDown(1.0f));
System.out.println(Math.nextDown(1.0));
System.out.println(Math.nextDown(0.5f));
System.out.println(Math.nextDown(0.5));
System.out.println(Math.nextDown(Math.PI));
System.out.println(Math.nextDown(3.1415927f));
Definition and Usage
The nextDown()
method returns the floating point number adjacent to a number in the negative direction, which is the highest possible floating point number that is less than the starting number.
The return value for double
type arguments will be closer to the starting number than the return value for float
type arguments.
Syntax
One of the following:
public static double nextDown(double start)
public static float nextDown(float start)
