Maybe someone here knows.

In merging Excel data to a sheet in MS Word, the original numbers in
Excel are very simple:
examples: 2.16 or 4.98 or 108.45. (I've even re-entered the numbers in
this column to be just sure the data length is as shown.)
However, upon merging the column containing these numbers, the
resulting display is something like 2.1599999999999974+2 or
4.9799999999999999.

I looked briefly at Word's MERGEFIELD, but the nomenclature for
inserting a switch was not very clear. This is a head scratcher. Any
ideas?
