Not burying, just moving it to the correct subforum and merging it with a recent similar topic. If I had wanted to bury it, I'd simply have locked or deleted it.
As discussed in the threads linked above, the main problem is not the math, it's the fact that the UI can't know when you swing.
If you only want the number and nothing else that's doable. Math may be a problem with the first two DynamicData items if they are just strings, but I don't know whether they are without testing. Of course you can just have the user enter them as well.
