−Currying changes the function's shape. Transforming (rate, price) => ... into rate => price => ... makes the result of the first call a function waiting for the second argument. Supplying only the first argument to that curried function is partial application, which is why the terms often get mixed up: one is a transformation, the other fills in arguments.
