Java 中的 StrictMath nextUp()方法
原文:https://www . geesforgeks . org/strict math-nextup-method-in-Java/
-
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().
语法:
java public static double nextUp(*double num*)参数:该方法接受双类型的一个参数数，该参数为起始浮点值。
返回值:该方法返回接近正无穷大的相邻浮点值。它有三种特殊情况:
- 当参数是 NaN 时，结果是 NaN。
- 当数为正无穷大时，返回正无穷大..
- 结果是双倍。参数为零时的最小值。
示例:
```java Input: num = 25.18700000 Output: 25.187000000000005
```
下面的程序说明了 Java.lang.StrictMath.nextUp()方法:
```java // 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:
```java 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.
语法:
java public static float nextUp(*float num*)参数:该方法接受一个浮点类型的参数数，该参数为起始浮点值。
返回值:该方法返回接近正无穷大的相邻浮点值。它有三种特殊情况:
- 当参数是 NaN 时，结果是 NaN。
- 当数为正无穷大时，返回正无穷大..
- 结果是“浮动”。参数为零时的最小值。
示例:
```java Input: num = 15.78f Output: 15.780000686645508
```
下面的程序说明了 Java.lang.StrictMath.nextUp()方法:
```java // 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:
```java The Next upper value is : 73.7280044555664 The Next upper value is : 51.71000289916992 The Next upper value is : 1.401298464324817E-45
