It looks like you are trying to use x^y to compute x to the power y, but 
that's not what ^ does in C++, it is a XOR, which doesn't make much sense 
for floats.

Currently, you need to use the C interface to compute a power. In the 
future, the C++ interface might overload the function 'pow', in which case 
you would be able to call pow(x,y).
