- The nextAfter(double start, double direction) is the inbuilt method of StrictMath class in Java which is used to get the float number, adjacent to the start in the direction of the second argument direction. This method gives rise to few conditions depending on the type and variation of parameters.
- The result is the second argument when both the arguments are equal.
- The result is NaN when any one of the arguments is a NaN.
- The result is the direction without any change when both arguments are signed zeros.
- The result is a zero with the same sign as start when start is ±Double.MIN_VALUE and direction has a value such that the result has a smaller magnitude.
- The result is the Double.MAX_VALUE with the same sign as start when start is infinite and direction has a value such that the result should have a smaller magnitude.
- The result is an infinity with same sign of start when start is equal to ±Double.MAX_VALUE and direction has a value such that the result should have a larger magnitude.
Syntax:
public static double nextAfter(double start, double direction)
Parameters: The method accepts two parameters:
- start: This is of double type which refers to the starting floating-point value.
- direction: This is of double type and refers to the value which indicates whether the start’s neighbors or start should be returned.
Return Value: The method returns the floating point number that is adjacent to start in the direction of direction.
Examples :
Input: start = 72.74d direction = 1.2d Output: 72.73999999999998Below programs illustrate the java.lang.StrictMath.nextAfter() method:
