#1197 closed defect (fixed)

Rounding effects may cause the mRNA protocol to incorrectly display "Large mix"

Description

The volume to use from an RNA is calculated by using the stored values for concentration and used quantity. For pre-normalized items this should be equal to the target volume used by the mRNA protocol (eg. 50µl). As usual with calculations involving floating point numbers the result is not exact and if we, for example, get the result 50.000000000001 the protocol will display "Large mix; use 50µl". It doesn't affect actual functionality.

Fixes #1197: Rounding effects may cause the mRNA protocol to incorrectly display "Large mix"

When comparing volumes we use an accuracy parameter of 0.05.
