- 此方法返回指定double值的反正切值。
例子 (Example)
public class Test {
public static void main(String args[]) {
double degrees = 45.0;
double radians = Math.toRadians(degrees);
System.out.format("The value of pi is very very very approximately %.4f%n", Math.PI);
System.out.format("The arctangent of %.4f is %.4f degrees %n", Math.cos(radians),
Math.toDegrees(Math.atan(Math.sin(radians))));
}
}
这将产生以下结果 -
输出 (Output)
The value of pi is very very very approximately 3.1416
The arctangent of 0.7071 is 35.2644 degrees
