The Java Math class provides several static methods that allows us to work on mathematical calculations with numbers. These methods can be accessed by using the Math class with a given method:

Math.method();

Math Constants

There are several mathematical constants defined in the Java Math class. These constants are marked as public static final, which means they are public, class-level constants with unchangeable values and can be accessed as follows:

Name	value	Definition
`Math.PI`	3.141592653589793	This constant represents the mathematical constant π (pi).
`Math.E`	2.718281828459045	This constant represents the base of the natural logarithm, also known as Euler’s number.

Math Methods

Here are the Math methods in alphabetical order:

Math Methods

.abs(): Returns the absolute value of the argument.
.acos(): Returns the inverse cosine of the argument in radians.
.addExact(): Returns the sum of its arguments.
.asin(): Returns the inverse sine of the argument in radians.
.atan(): Returns the inverse tangent of the argument in radians.
.atan2(): Returns the counterclockwise angle, in radians, between a (x,y) point and the positive x-axis.
.cbrt(): Returns the cube root of a double-type value.
.ceil(): Returns the double value that is a mathematical integer and is greater than or equal to the original value.
.cos(): Returns the trigonometric cosine of the specified angle.
.decrementExact(): Returns the argument decremented by one, throwing an exception if the result overflows the datatype.
.floor(): Returns the largest integer value that is less than or equal to the argument. When the provided value is either an integer, zero, not a number, or positive or negative infinity.
.hypot(): Returns the hypotenuse of a right-angled triangle.
.incrementExact(): Returns the argument incremented by one, throwing an exception if the result overflows the datatype.
.log(): Returns the natural logarithm (base e) of a double value as a parameter.
.log10(): Returns the logarithm base 10 of a double value as a parameter.
.log1p(): Returns the natural logarithm (base e) of the sum of a double value as a parameter and 1.
.max(): Returns the maximum value from the given two arguments.
.min(): Returns the minimum value from the given two arguments.
.multiplyExact(): Returns the product of its arguments.
.negateExact(): Returns the negation of the argument and raises an exception if the result overflows.
.nextAfter(): Returns the floating-point number next to the first argument in the direction of the second argument.
.nextDown(): Returns the floating-point value adjacent to the parameter provided in the direction of negative infinity.
.pow(): Returns the first argument raised to the power of the second argument.
.random(): Returns a pseudorandom double that is 0.0 or greater, and less than 1.0.
.rint(): Returns a double that is rounded to the closest whole integer.
.round(): Returns an int or long value that is closest to the number provided.
.scalb(): Returns the first argument multiplied by 2 to the power of the second argument.
.signum(): Used to determine whether a number is positive, negative, zero, or NaN.
.sin(): Returns the trigonometric sine of the specified angle.
.sinh(): Returns the hyperbolic sine of a double-type value.
.sqrt(): Returns the positive, properly rounded square root of a double-type value.
.tan(): Returns the tangent of an angle given in radians.
.tanh(): Returns the hyperbolic sine of a double-type value.
.toDegrees(): Returns an angle measurement converted from radians to degrees.
.toIntExact(): Returns the integer value of a long type argument. An exception is thrown if the value of argument overflows that of an int.
.toRadians(): Converts an angle in degrees to an approximately equivalent angle in radians.
.ulp(): Returns the size of the unit of last precision of a number.
