最后,第十五、十六行调用Math类中的sqrt方法,求出4的平方根,并输出结果 "Square root of 4.0 is 2.0"。 小结 本文介绍了Java中的Math类,包括定义、源代码解析、应用场景案例、优缺点分析、类代码方法介绍、测试用例等。Math类提供了一系列与数学计算相关的方法,可以方便地进行数学计算。但是,Math...
int num = -10;int absNum = Math.abs(num);System.out.println("Absolute value of " + num + " is " + absNum); 2、平方根(Square Root) double number = 25;double sqrtNum = Math.sqrt(number);System.out.println("Square root of " + number + " is " + sqrtNum); 3、取整(Rounding...

the positive square root of a. If the argument is NaN or less than zero, the result is NaN. cbrt public static double cbrt(double a) Returns the cube root of a double value. For positive finite x, cbrt(-x) == -cbrt(x); that is, the cube root of a negative value is the negat...
Math类是Java中的一个final类,即无法被继承。它的源代码如下: public final class Math { // 省略部分代码 /** * Returns the trigonometric sine of an angle. * * @param a an angle, in radians. * @return the sine of the argument.
the positive square root of a. If the argument is NaN or less than zero, the result is NaN. cbrt public static double cbrt(double a) Returns the cube root of a double value. For positive finite x, cbrt(-x) == -cbrt(x); that is, the cube root of a negative value is the negat...
