Analysis

Cause

All calculations within Qtegra are performed at the full available precision of the computer’s floating point unit. It is only when results are displayed in Qtegra that they are truncated to value specified in Concentration Precision Digits (max value of 8). The values displayed in Qtegra are always stored (and calculated) with their full precision, regardless of how they have been formatted for display purposes.
