Hi Winfried,

I'm currently implementing the new FORECAST functions that are added to Excel 2016.

Great! :)

Mostly they use triple exponential smoothing.
To avoid double work, am I correct that the current LO codebase does not contain code that uses 
triple exponential smoothing?

I'm quite sure we don't have such. Not even double I guess ;-)
The only place I ran across exponential smoothing was
sc/source/ui/StatisticsDialogs/ExponentialSmoothingDialog.cxx
ScExponentialSmoothingDialog::ApplyOutput()

I would also like to create a new source file, sc/source/core/tool/interpr8.cxx, as probably a 
lot of code lines will be added, all specifically for FORECAST.ETS functions. Any objections to 
that?

No, please go ahead. Would be good to have every new code related in one
place and in a separate file.

Btw, do you have access to Excel 2016 to compare results?
