Remarks
The data type of the result is always 64-bit floating point.
The structure of the result corresponds to that of the argument Number. The calculation is done element-by-element where appropriate.
The result has the unit 1, if Number has a unit. Otherwise, it has no unit.
For aggregate data structures, only the Y component is calculated.
The following illustration shows the course of the function within the interval [-50, 50]:
If the argument is a list, then the function is executed for each element of the list and the result is also a list.
For complex data types the absolute value is formed.
