Java中的Math類的常用方法

1.三角函數(shù)

public static double sin(double a);

public static double cos(doublc a);

public static double tan(double a);

public static double asin(double a);

public static double acos(double a);

public static double atan(double a);

2.指數(shù)函數(shù)

public static double exp(double a):ea

public static double log(double a):ln(a)

public static double pow(double x,

                   double y):                  yx

public static double sqrt(double a):

3.舍入函數(shù)

public static int ceil(double a):返回大于或等于a的最小整數(shù)

public static int floor(double a):返回小于或等于a的最大整數(shù)。

public static int abs(int a)

public static int max(int a,int b)

public static int min(int a,int b)

4.其它方法

public static double random():返回0至1之間的一個“隨機數(shù)”。

public static double toRadians(double angle):將角度轉換為弧度

public static double toDegrees(double angle):將弧度轉換為角度。
