【描述】 定义方法:public static double squareRoot(double value),返回value的平方根。 编写一个main方法,读入一个数,调用squareRoot方法,输出该数的平方根。 可以通过对下面公式的反复计算近似地得到平方根: 当nextGuess和lastGuess几乎相同时,nextGuess就是平方根的近似值。nextGuess最初的猜测值可以是任意一个值...

以下是使用二分查找法逼近开方值的代码示例: doublenumber=16;doublelow=0;doublehigh=number;doubleprecision=0.00001;while(high-low>precision){doublemid=(low+high)/2;doublesquare=mid*mid;if(square>number){high=mid;}else{low=mid;}}doublesquareRoot=(low+high)/2;System.out.println("平方根为:"+sq...
getValueAsString():将当前令牌作为字符串返回。 getValueAsInt():将当前令牌作为整数返回。 JsonGenerator:用于将JSON数据写入数据源(如文件、输出流或字符串缓冲区)。主要方法有: writeStartObject():写入开始对象标记({)。 writeFieldName(String):写入字段名称。

So, it’ll need fewer iterations to get the square root: public class BinarySearchRange { private long low; private long high; // standard constructor and getters } private void initiateOptimizedBinarySearchLookupTable() { lookupTable.add(new BinarySearchRange()); lookupTable.add(new BinarySearch...

sqrt(double a) Returns the correctly rounded positive square root of a double value. static double tan(double a) Returns the trigonometric tangent of an angle. static double tanh(double x) Returns the hyperbolic tangent of a double value. static double toDegrees(double angrad) Converts an angl...
Note:The valid values ofNchange for each release, with new values added and old values removed. You'll get an error message if you use a value ofNthat is no longer supported. The supported values ofNare the current Java SE release (17) and a limited number of previous releases, detailed...
