### Sub-precision values

Sub-precision values are those values that would give a value of zero when expressed as percentages, when rounded down. This can be misleading if the results tables shows non-zero results.

The following tables demonstrate the effect of selecting and deselecting the Mark sub precision values checkbox when the precision set to the lowest level. A frequency of 3 in 347 corresponds to 0.86%. With Mark sub precision values deselected, this value is displayed as 0%; if Mark sub precision values is selected, the value is displayed as <1%, which most users will find more informative.
