[dgleich]

Titles says it all. Base now has tanpi and this should extend that function.

Just importing tanpi does not provide a DoubleFloat version of tanpi. What is the intent?

[dgleich]

There's already a tanpi function for double floats. This just extends the base method instead of exporting a new method.
