How to use nextDown() in Java
Fouzia BashirnextDown() is a built-in method of the java.lang.Math library. It returns the value adjacent to the n argument in the direction of negative infinity (-∞).
Syntax
The example below is used for primitive double type argument:
static double nextDown(double n)
The example below is used for primitive float type argument:
static float nextDown(float n)
Parameter
n can be a double or float value.
Return value
This function returns the value adjacent to n (double or float) in the direction of (-∞).
Special cases
- If the parameter’s value is NaN, then the function will return NaN.
- If we pass zero as an argument while dealing with type double, then this function will return
Double.MIN_VALUE. - When we are dealing with float and the argument is zero,the result will be
Float.MIN_VALUE. - If we pass negative infinity as an argument, then the return value will be negative infinity.
Code
public class EdPresso
{
public static void main(String[] args)
{
double y = 0.0;
// the argument is zero, the return value is Double.MIN_VALUE
System.out.println(Math.nextDown(y));
y = 0.0/0;
// the argument is NaN, the return value is NaN
System.out.println(Math.nextDown(y));
y = 865.78;
// the argument is of type double, the return value is the adjacent double value in the direction of negative infinity
System.out.println(Math.nextDown(y));
y = -865.78;
// the input of argument is zero, result: Float.MIN_VALUE
System.out.println(Math.nextDown(y));
float x = 0.0f;
// the argument is zero, the return value is Float.MIN_VALUE
System.out.println(Math.nextDown(x));
}
