[Boost-users] boost::bind

Dear Users, I am using bind to calculate the transform of an initial vector in its element by element power (to a given exponent). I used this syntax std::transform(values.begin(), values.end(), values.begin(),boost::bind(pow,_1,exponent)); but the compiler complains for with error C2780 : expects 2 arguments 3 provided... Do you have any solution/explanation? Thanks in adavnce!
