I need a rather simple math/calculation algorithm (at least for someone who is good with this kind of thing) It would be great if it could be done as a function in Delphi, but as long as I can convert it from another programming language (C,C++,VB) that's fine. There will be a few different numbers inputted to it & I need a single value returned. To be more specific, it's to make a buying decision on a product based on the inputs. Those inputs would be: - An average buy price for the product - The last known (but possibly not accurate) "lowest" buy price for the item - A "risk" level (very low to very high, see details) I basically need it to output a price based on those 3 things that would be a good/safe price to make a profit.
