Thanks for the clarification !

My interpretation from Erika's mail, is that the analyte result is
already computed and is given as a number, with n decimals (there is
no computation). She wants to make sure there is no rounding in the
decimals needed.
So, in this case, we should use the current Fields.Float that we have
for the result, and specify the decimal precision.

My main concern with this though is the initial comment. We don't want
to clutter the result with extra digits that can actually lead to
misinterpretation from the (human) reader.
