StrictMath nextUp() Method in Java Improve Improve Like Article Like Save Share Report The nextUp(double num) is an inbuilt method of StrictMath class in Java which is used to get the float value that is contiguous to num in the direction of positive infinity. The nextup() method is equivalent to nextAfter(num, Double.POSITIVE_INFINITY) but nextup() runs faster than nextAfter(). Syntax: public static double nextUp(double num) Parameters: The method accepts one parameter num of double type which is the starting floating point value. Return Value: The method returns the adjacent floating-point value closer to positive infinity. It has three special cases: The result is NaN when argument is a NaN. It returns positive infinity when the num is positive infinity.. The result is Double.MIN_VALUE when the argument is zero. Examples: Input: num = 25.18700000 Output: 25.187000000000005 Below program illustrates the Java.lang.StrictMath.nextUp() Method: // Java praogram to illustrate the // Java.lang.StrictMath.nextUp() Method import java.lang.*; public class Geeks { public static void main(String[] args) { double num1 = 67.1230000000; double num2 = 21.12, num3 = 0.0; // Returns floating-point value adjacent to num double nextUp_Value = StrictMath.nextUp(num1); System.out.println("The Next upper value is : " + nextUp_Value); double nextUp_Value1 = StrictMath.nextUp(num2); System.out.println("The Next upper value is : " + nextUp_Value1); double nextUp_Value2 = StrictMath.nextUp(num3); System.out.println("The Next upper value is : " + nextUp_Value2); } } Output: The Next upper value is : 67.12300000000002 The Next upper value is : 21.120000000000005 The Next upper value is : 4.9E-324 The nextUp(float num) is the inbuilt method of StrictMath class in Java which is used to get the floating point value that is adjacent to num in the direction of positive infinity.Float.POSITIVE_INFINITY) but nextup() runs faster than its equivalent nextAfter call. Syntax: public static float nextUp(float num) Parameters: The method accepts one parameter num of float type which is the starting floating point value. Return Value: The method returns the adjacent floating-point value closer to positive infinity. It has three special cases: The result is NaN when argument is a NaN. It returns positive infinity when the num is positive infinity.. The result is Float.MIN_VALUE when the argument is zero. Examples : Input: num = 15.78f Output: 15.780000686645508 Below program illustrates the Java.lang.StrictMath.nextUp() Method: // Java praogram to illustrate the // Java.lang.StrictMath.nextUp() Method import java.lang.*; public class Geeks { public static void main(String[] args) { float num1 = 73.728f; float num2 = 51.71f, num3 = 0.0f; // Returns floating-point value adjacent to num double nextUp_Value = StrictMath.nextUp(num1); System.out.println("The Next upper value is : " + nextUp_Value); double nextUp_Value1 = StrictMath.nextUp(num2); System.out.println("The Next upper value is : " + nextUp_Value1); double nextUp_Value2 = StrictMath.nextUp(num3); System.out.println("The Next upper value is : " + nextUp_Value2); } } Output: The Next upper value is : 73.7280044555664 The Next upper value is : 51.71000289916992 The Next upper value is : 1.401298464324817E-45 Last Updated : 03 Aug, 2018 Like Article Save Article Previous StrictMath tanh() Method in Java Next GregorianCalendar clone() Method in Java Share your thoughts in the comments Add Your Comment Please Login to comment...
