r/javahelp on Reddit: How does Java calculate Math.pow(a,b) and how do I figure out how to figure out how it does it?
June 10, 2015 -
Hello,
I'm trying to create a method to calculate exponents through addition and factorial instead of multiplication to compare it to the "usual" Math.pow approach. My problem is that Math.pow only works with doubles and I need bigger numbers to actually see any differences.
What does Math.Pow(x,2) do under the hood, that is much slower than x*x?
Math.Pow needs to be able to raise any number to the power of any other number, not just 2. It's instrinsically a much slower computation than just multiplying one number by another. CPUs generally don't even have a single instruction for raising an arbitrary number to an arbitrary power - they have instructions for taking natural logarithms, and raising e to the power of some number, so they combine them to do: y = e^(n*ln(x)) More on reddit.com
Math.pow
The math.pow() function can be used to raise a number to a power and takes in two parameters - the base and the power that you'd like to raise the base to. Here's a link to some documentation on the math.pow() function in C# from the GeeksforGeeks.org website that explains how the function works and provides some examples of how it can be used. A quick example would be using the math.pow() function to square a number. If we wanted to find out what 52 is, we could do something like this: double result = math.pow(5, 2);. This would store the result (25) in the result variable. You could then print the value of result to the screen or use it elsewhere in your program. More on reddit.com

Java Math.pow() Explained: The Java Power Function
January 7, 2026 - A negative base with a non-integer exponent typically returns NaN (e.g., Math.pow(-4, 0.5) → square root of negative). Bases of magnitude greater than 1 raised to +Infinity return +Infinity. Bases between 0 and 1 raised to +Infinity return +0.0. Overflow results in +Infinity or -Infinity; underflow results in +0.0 or -0.0. ... java System.out.println(Math.pow(Double.NaN, 5)); // NaN System.out.println(Math.pow(-4, 0.5)); // NaN System.out.println(Math.pow(0, 0)); // 1.0 System.out.println(Math.pow(2, Double.POSITIVE_INFINITY)); // Infinity

July 16, 2024 - Exponential Calculation: Finally, the exponential function (exp) is applied to the product of the logarithm and the exponent. This function raises the constant e (approximately 2.71828) to the power of the product, yielding the final result. Java’s Math.pow() method is designed to be efficient, leveraging hardware-level instructions when available.

It may have been written down as 1.210,1.210000000,1.21000000000 because a 0 after a decimal place is an insignificant figure. But, from where does this 2 come in the answer thrown by Math.pow(). This might be a very silly question, but I am curious to enough as to know, why this happens. Regards, Ranajoy ... Actually, it is a question of precision - of Java's double data type.
