Learn the RESHADED framework for architecting web-scale applications by determining requirements, constraints, and assumptions before diving into a step-by-step design process.
The nextDown
method returns the next adjacent number (floating-point value) of the argument in the direction of negative infinity.
float Math.nextDown(float num);
double Math.nextDown(double num);
num
: The number for which the next adjacent number in the direction of negative infinity is to be returned. num
can be either float or double.
Returns the next adjacent number of the argument in the direction of negative infinity.
Returns NaN
if the argument is NaN.
Returns -Float.MIN_VAL
if the argument type is float and the value of the argument is 0
.
Returns -Double.MIN_VAL
if the argument type is double and the value of the argument is 0
.
Returns -Infinity
if the argument passed is negative infinity.
class HelloWorld {public static void main( String args[] ) {float num = 10.0f; // we can als use double type with Math.nextDownSystem.out.println("Math.nextDown(10.0) = " + Math.nextDown(num));num = 10.000001f;System.out.println("Math.nextDown(10.000001f) = " + Math.nextDown(num));num = -(1.0f/0.0f); // negative infinitySystem.out.println("Math.nextDown(-(1.0/0.0)) = " + Math.nextDown(num));num = 0;System.out.println("Math.nextDown(0) = " + Math.nextDown(num));System.out.println("Math.nextDown(0) == -Float.MIN_VALUE :" + (Math.nextDown(num) == -Float.MIN_VALUE));}}
In the code above, we used the Math.nextDown
function to find the next adjacent floating-point value of the arguments in the direction of negative infinity.
For the number 10.0
, the next adjacent floating-point value is 9.999999
.
For the number 10.0000001
, the next adjacent floating-point value in the negative infinity direction is 10.0
.
For the number -(1.0/0.0)
(negative infinity), the next adjacent floating-point value in the negative infinity direction is -infinity
.
For the number 0
, the next adjacent floating-point value in the negative infinity direction is -Float.MIN_VALUE (-1.4E-45)
.
