System.out.println(Math.nextAfter(1, 2));
System.out.println(Math.nextAfter(1, 0));
System.out.println(Math.nextAfter(0.5f, 1.0f));
System.out.println(Math.nextAfter(0.5f, 0.0f));Definition and Usage
The nextAfter() method returns the floating point number adjacent to a number x in the direction of a number y.
If y is greater than x then it looks for the lowest possible floating point number that is greater than x. If y is less than x then it looks for the highest possible floating point number that is less than x. If y is equal to x then this method returns x. The return value for double type arguments will be closer to x than the return value for float type arguments. Syntax One of the following: public static double nextAfter(double x , double y ) public static float nextAfter(float x , double y ) Parameter Values Parameter Description x Required. The number to start from. y Required. The direction to step towards. Technical Details Returns: A double or float value representing the next floating point number from a starting point in a specified direction. Java version: 1.6+ ❮ Math Methods
