Arithmetic calculation

Sometimes, it might be useful to manipulate data by general mathematical operations like adding, subtracting, multiplying or dividing by a constant value to adapt data to a similar object. For this purpose several arithmetic functions can be used. By default all objects in the current dataview will be processed. If only the selected active object needs to be processed, the user must activate the option ApplyOnActiveSpectrumOnly.
