Outputs the absolute value of an input signal.

The absolute value is defined as:

When Input >= 0, Abs() = Input

When Input < 0, Abs() = -1 * Input

Absolute values are often used to compare the difference between signals or on flowrates and velocities, which can become negative during flow reversals.



Input Data*

Defines the time series data fed into the function. This can be a sensor ID or another function.

*Input data is optional in most cases. If Info360 detects that the first input is time series data, it will be applied to the function. Otherwise, the current active sensor's data will be used, which is often the case in Reference Charts.

Example Usage as an Expression:

Abs(ROC(5)) - returns the absolute value of the ROC over the past 5 intervals.

Example Reference Chart:

The following simple example shows how Abs() is the same as the input signal when positive, and the positive opposite of the input when the input is negative.
