Glitches a lot
Gives different profit values for same numbers that were inputted.Sometimes it cancels out purchase cost to zero. Overall itโs very inaccurate the majority of the time
Doesnโt do decimal points
Whatโs the point in this if you canโt accurately calculate
Math Wrong
If input item cost, output should take into account item cost in results. Your app dismisses item cost as zero, thus calculations become invalid and wrong. This is a simple fix.
