Babylonian Square Root Write a Java program to find the square root of a number using the Babylonian method. Sample Solution: Java Code: importjava.util.*;publicclasssolution{publicstaticfloatsquare_Root(floatnum){floata=num;floatb=1;doublee=0.000001;while(a-b>e){a=(a+b)/2;b=num/a;}...
// square root of a positive number System.out.println(Math.sqrt(value2)); // 5.0 // square root of a negative number System.out.println(Math.sqrt(value3)); // NaN // square root of zero System.out.println(Math.sqrt(value4)); // 0.0 } } Run Code In the above exam...
在Java中,开方函数通常使用Math类的sqrt()方法。这个方法可以计算一个数字的平方根。 例如: ```java double number = 25.0; double squareRoot = Math.sqrt(number); System.out.println("平方根是: " + squareRoot); ``` 这段代码会输出`平方根是: 5.0`,因为25的平方根是5。 注意,sqrt()方法不能...
Accuracy of the floating-point Math methods is measured in terms of ulps, units in the last place. For a given floating-point format, an ulp of a specific real number value is the distance between the two floating-point values bracketing that numerical value. When discussing the accuracy of...
