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)Parameter Values
| Parameter | Description |
|---|---|
| start | Required. The number to start from. |
Technical Details
| Returns: | A double or float
value representing the floating point number adjacent to a starting number in the negative direction. |
