Java Math Pow

Unlike some of the numeric methods of class strictmath all implementations of the equivalent functions of class math are not defined to return the bit for bit same results.

Java math pow.

The math pow function returns the base to the exponent power that is base exponent the base and the exponent are in decimal numeral system. If either the base value or exponent value argument is not a number java math pow will return the result as nan. Please note that the int casting in the above example is required if we want to have an integer result. If the second argument is positive or negative zero this.

If the second argument is 1 0 then the result is the same as the first argument. Because pow is a static method of math you always use it as math pow rather than as a method of a math object you created math has no constructor. The output will be 74 08800000000001. If the exponent value is positive or negative zero math pow in java will return the result as 1 0.

Int intresult int math pow 2 3. Special cases if the second argument is positive or negative zero then the result is 1 0. Unlike some of the numeric methods of class strictmath all implementations of the equivalent functions of class math are not defined to return the bit for bit same results. The output will be 8.

Let s now pass a double as an argument and see the results. When the absolute value of base value is equal to one and the exponent value is infinity then math pow in java returns the result as nan. Double dblresult math pow 4 2 3. The class math contains methods for performing basic numeric operations such as the elementary exponential logarithm square root and trigonometric functions.

This method returns the value of a b. In math 2 8 2x2x2x2x2x2x2x2 256 in java math pow 2 8 note in java the symbol is a xor operator don t use this for the power calculation. The java lang math pow is used to return the value of first argument raised to the power of the second argument. The java lang math pow is used to calculate a number raise to the power of some other number.

If the base is negative and the exponent is. This function accepts two parameters and returns the value of first parameter raised to the second parameter. This relaxation permits better performing implementations. There are some special cases as listed below.

The class math contains methods for performing basic numeric operations such as the elementary exponential logarithm square root and trigonometric functions. The java lang math pow double a double b returns the value of the first argument raised to the power of the second argument.
