double "^" operations ???...

[adam.balgach]

Greetings all,

I am having a hard time performing exponential operations on doubles.
My code looks like

public double getExpon(double a, double b) {
double ans = a ^ b;
return(ans);
}

and I am getting the compiler error:

operator ^ cannot be applied to double,double
double ans = a^b;


Does anyone know why? I am totally bewildered.

Never mind, I forgot you have to use Math.pow(a,b)

and not a^b [bitwise OR operation?]

^ isn't exponentiation in Java; it's (integer) XOR.

Check out Math.exp
