20.3.26 Root function details
20.3.26.1 Behaviour
The module calculates the nth root of the input value and outputs it as result on the Output 0 .
If a negative input value is present on the input, the value 1 (logical "true") is output on the Out-
put 1 . In this case, no value is output on the Output 0.
The internal data type of this module is Number. If necessary, incoming values are converted
into the internal data type before the calculation (see conversion table below).
20.3.26.2 Extended settings
You can specify to which exponent the root shall be calculated (e.g. 2 for square
