Signals Notebook: Only shows one decimal number and rounds it up to this.

It seems the number of decimal digits you receive at the end will depend on the number of significant figures (sf) in the values the user enters.

EXAMPLES:

1. They have a reagent with a FM of 232.06. If they add 0.6 mol (1 sf) that equates to 0.6x232.06 g = 139.236g. In kg that is 0.13926, which to 1 sf is 0.1 kg.

In reverse, if they specify 0.1kg then that is 100g/232.06 = 0.4309 mol = 0.4 mol to 1 sf.

The system is doing what is mathematically appropriate, which is reflecting the same level of accuracy as their least accurate user entered value. If they changed the accuracy of their entered value as follows they would see a different accuracy:

2. They have a reagent with a FM of 232.06. If they add 0.60 mol (2 sf) that equates to 0.6x232.06 g = 139.236g. In kg that is 0.13926, which to 2 sf is 0.14 kg.

In reverse, if they specify 0.10 kg then that is 100g/232.06 = 0.4309 mol = 0.43 mol to 2 sf.

3. They have a reagent with a FM of 232.06. If they add 0.600 mol (3sf) that equates to 0.6x232.06 g = 139.236g. In kg that is 0.13926, which to 3 sf is 0.139 kg.

In reverse, if they specify 0.100 kg then that is 100g/232.06 = 0.4309 mol = 0.431 mol to 3 sf.
