Java Math Class :
  • For scientific and engineering calculations, a variety of mathematical functions are required.
  • Java provides these functions in the Math class available in java.lang package.
  • The methods defined in Math class are given following:
Method Description
Double sin(double x) Returns the sine value of angle x in radians.
Double cos(double x) Returns the cosine value of the angle x in radians
Double tan(double x) Returns the tangent value of  the angle x in radians
Double asin(double x) Returns angle value in radians for arcsin of x
Double acos(double x) Returns angle value in radians for arcos of x
Double atan(double x) Returns angle value in radians for arctangent of x
Double exp(double x) Returns exponential value of x
Double log(double x) Returns the natural logarithm of x
Double pow(double x, double y) Returns x to the power of y
Double sqrt(double x) Returns the square root of x
Int abs(double n) Returns absolute value of n
Double ceil(double x) Returns the smallest wholoe number greater than or equal to x
Double floor(double x) Returns the largest whole number less than or equal to x
Int max(itn n, int m) Returns the maximum of n and m
Int min(int n, int m) Returns the minimum of n and m
Double rint(double x) Returns the rounded whole number of x
Int round(float x) Returns the rounded int value of x
Long round(double x) Returns the rounded int value of x
Double random() Returns a random value between 0 and 1.0
Double toRandians(double angle) Converts the angle in degrees to radians
Double toDegrees(double angle) Converts the angle in radians to degrees

EX :


 

Output :
120.0 degrees is 2.0943951023931953 radians.
1.312 radians is 75.17206272116401 degrees.
