Dec 19, 2012 · Here is my code. For some reason my BMI is not calculated correctly. When I check the output on a calculator for this : (10/((10/100)^2))) I get 1000, but in my program, I get 5.

Feb 19, 2019 · Unlike Python (where powers can be calculated by a**b) , JAVA has no such shortcut way of accomplishing the result of the power of two numbers. Java has function named pow in the Math class, which returns a Double value

Nov 1, 2014 · In Java, we throw an exception in such a case. The most appropriate ready-made exception is IllegalArgumentException. It's a RuntimeException, so you don't need to add a throws clause to your method. It would be good if you either caught it or prevented such a situation from happening, in your main method when you read in the arguments.

Apr 6, 2014 · I am having a really hard time creating a method to raise a matrix to the power. I tried using this . public static int powerMethod(int matrix, int power) { int temp = matrix ; for (int i = power; i == 1; i--) temp = temp * matrix ; return temp ; but the return is WAYYY off. Only the first (1,1) matrix element is on point.

Nov 18, 2021 · The advantage of this method is that there is no need to define a precision. However, we need to perform another pow operation so this will affect performance. Option 3. There is no built-in method to calculate a double power of a BigDecimal. This question will give you insight on how to do it.

Apr 23, 2011 · Additionally for what was said, if you want integer powers of two, then 1 << x (or 1L << x) is a faster way to calculate 2 x than Math.pow(2,x) or a multiplication loop, and is guaranteed to give you an int (or long) result.

The myPow(double, double) method signature implies it calculates with floating point powers while in fact it doesn't. The method signature should read myPow(double, int). Math.pow(double, double) does take floating point powers into account, e.g., Math.pow(4, 0.5) returns the square of 4, so 2, whereas myPow(4, 0.5) would return 4.

May 14, 2012 · It is the default answer so it will be used only when you don't stub the method call. The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value.

Oct 17, 2013 · I've been trying to write a simple function in Java that can calculate a number to the nth power without using loops. I then found the Math.pow(a, b) class... or method still can't distinguish the two am not so good with theory. So i wrote this..

Nov 11, 2015 · Trying a method to find the power of a number using a for loop and without using Math.pow. For this result I just got 2.0 as it doesn't seem to go back round through the loop.
