Signals Notebook: How can I have more digits after decimal separator in the calculated amount of reagents

Calculations in Signals Notebook are ruled by significant digits. If you want 3 significant digits in volume, you need to provide minimum 3 significant digits in all values from which volume will be calculated. For example, with Sample Mass = 0.811 g and Density = 0.726 g/mL, it should calculate Volume = 1.12 mL.
