Looking it up, Excel says to treat the EUR target currency as if it could be used in triangulation, even if there was no triangulation. However, apparently TriangulationPrecision in this case is only used if given as argument, not the default value. Something we'll have to add to the spec. > 4.TriangulationPrecision's rang is 3~32767, this is not an important > thing, just mention to let know. That's probably more due to Excel interna, a 16-bit signed value. A precision that high doesn't make sense anyway. > somewhere I used "seem to", because I didn't find any more detailed > specifices of Excel's EUROCONVERT(), so I can only guess from the result > it gives.
