The expression is always a comparison. The comparison operator is within XML one of (.ne., .eq., .gt., .ge., .lt., .le.). Each variable has to be a single word without spaces. Mathematical symbols or functions like e, pi or cos cannot be used as variableId, but they will be interpreted mathematically.
Soem mathematical functions worth mentioning are the following (these must be in lowercase):
Function | Description |
|---|---|
avg(x1, x2, x3, ...) | Average |
min(x1, x2, x3, ...) | Minimum |
max(x1, x2, x3, ...) | Maximum |
abs( x ) | Absolute value |
round( x ) | Rounded value |
floor( x ) | Floor |
ceil( x ) | ceiling |
sin, cos, tan | Trigonometric |
mod( x , y) | x % y Modulus |
sqrt( x ) | SquareRoot |
sum( x, y,...) | Sum of multiple variables |
A simple configuration example for the seriesComparisonCheck is given below, it will make the workflow check the values that are reliable or doubtful, and mark them as unreliable if they are smaller than thirteen:
