Java toDegrees()方法示例
原文:https://www . geeksforgeeks . org/Java-todegrees-method-example/
java.lang.Math.toDegrees()用于将以弧度度量的角度转换为以度数度量的近似等效角度。
注:弧度到度数的转换一般不精确；用户不应该期望 cos(toRadians(90.0))正好等于 0.0。
语法 :
public static double toDegrees(double rad)
Parameter:
rad : This parameter is an angle in radians which
we want to convert in degrees.
Return :
This method returns the measurement of the angle
rad in degrees.
示例:展示Java . lang . math . todegrees()方法的工作。
// Java program to demonstrate working
// of java.lang.Math.toDegrees() method
import java.lang.Math;
class Gfg {
// driver code
public static void main(String args[])
{
// value of PI in degrees
double rad = Math.PI;
System.out.println(Math.toDegrees(rad));
// value of PI/2 in degrees
rad = (Math.PI) / 2;
System.out.println(Math.toDegrees(rad));
// value of PI/4 in degrees
rad = (Math.PI) / 4;
System.out.println(Math.toDegrees(rad));
}
}
输出:
180.0
90.0
45.0
