Raising a number to a power in Java (10 answers)

Closed 9 years ago.

As above, I'm trying to make a number to the power of a variable, but it's not working, and is producing the error "The operator ^ is undefined for the argument type(s) double, long".

Here's the line of code:

longSwordCost = 30*(1.3^longSwordCount);

Help!

You need public static double Math.pow(double a, double b):

The ^ is an XOR logic operator in Java.
