Value.  The price is computed on-the-fly as Buy/Shares (or

I can see what you're getting, but I don't understand it either.  If I
go in and modify it a second time I can get it to be 0.0417 shares at
187.05, for 7.80, which is certainly closer.

You might need to modify your account (or commodity) to accept a
larger significant digit calculation.  You might also want to file a
bug report about the initial math, because it shouldn't round to 0.04.
