The VAR formula allows you to Calculate the variance of two values. The Variance can be expressed as an absolute number or as a relative value.
Syntax
VAR
(Parameter0 - Parameter1) or in the case of a relative variance (Parameter0 - Parameter1) / Parameter1
Depending on the Display Value of the Pick List the variance can be displayed in different ways:
Variance (Default): Variance value will be displayed as (Parameter0 - Parameter 1) or (Parameter0 - Parameter 1) / Parameter 1 (in case of relative variance)
Base: Variance value will be displayed as Parameter 0
Reference: Variance value will be displayed as Parameter 1
These options are available from version 4.2.
Starting form version 4.3.1 Better/Worse variance representation can be used to display positive variance with positive sign and negative variance with minus sign.
