You can use more than two decimal places for quantities and sales lines

TimeKing currently rounds everything to two decimal places by default. For the materials they use, it would be helpful to record them with even greater precision.

Currently, it seems as though you can enter a number with more decimal places, but then the sales calculation is incorrect. The total price is then calculated based on a number with two decimal places.
0.175 × 5.72 = 1.001
Total = 1.03 (1.18 × 5.72)
