Returns number of decimals in atomic weight. Uncertainty is discarded. Used: when doing crude molar mass calculation (see {{Chem molar mass}}).

Returns: the lowest number of decimals in a formula.

For starters: (Jan 2019): single element.

Atomic weight values used:

1. When interval: conventional, abridged value.
2. When single number value: standard atomic weight (unabridged).
3. When no stable isotope: mass number (0 decimals).
Uncertainty, noted as Template:Val (Ni) or Template:Val (H, implicit Template:Val), is discarded (removed unused).
