This would be:
      M(computeProfit:and:) : (id)price : (id)totalcost

*However*, you can't cast a double to an id... [sigh]... I know of two
suggested workarounds:
      1. Wrap the double in an object, or
      2. Change the method signature to use double pointers.

Both workarounds have drawbacks, see
