UPDATE: In the online player, it does .000000000002 or something like that after the number. For it to work properly, download it. It works with negative exponents and to the power of 0. also fractions. Pretty simple, really. Just type in the base, then type in the exponent. It calculates the value using a simple formula: x^y=e^y(ln(x)). (e is Euler's number). Deriving the formula from the formula e^ln(x)=x is shown below: e^ln(x)=x. x^2=x*x=(e^ln(x))*(e^ln(x)) Since x^a*x^b=x^(a+b), (e^ln(x))*(e^ln(x))= (e^ln(x))+(e^ln(x)) =e^2(ln(x)). So, x^y=e^y(ln(x)). Then you can calculate exponents quickly using the built-in "e^" function instead of using slow and unreliable methods like manually multiplying the number by itself. :)
