System.out.println(Math.nextUp(1.0f));
System.out.println(Math.nextUp(1.0));
System.out.println(Math.nextUp(0.5f));
System.out.println(Math.nextUp(0.5));
System.out.println(Math.nextUp(Math.PI));
System.out.println(Math.nextUp(3.1415927f));Definition and Usage
The nextUp() method returns the floating point number adjacent to a number in the positive direction, which is the lowest possible floating point number that is greater 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 nextUp(double start ) public static float nextUp(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 positive direction. Java version: 1.6+ ❮ Math Methods
