Eden,

The whole point of scientific (and engineering notation) is the wide
range over which numbers can be displayed with a specified number of
significant digits. Mathcad's inability to correctly display very small
numbers defeats the whole purpose of scientific and engineering
notation.

I'm unclear what the original problem is supposed to be. What did you
think should be displayed? You have "Show trailing zeros" checked for
all results and the number of zeros displayed correspond to the choice
selected. If you reset the results settings, the results show up as
"0", since the sheet default zero tolerance is 15.

The "anomalous" 1 in the 15th decimal place is a consequence of
selecting a number that is not exactly represented by binary fractions.

TTFN,
Eden

I am having trouble with getting Mathcad 14 to display results
correctly.

In some cases, the exponential threshold does not work except
when 17
decimal places are selected to be displayed, but even then
additional
numbers appear in the result at the 14th or 15th decimal places.

I did a "mathcad /register" from the command line in the Mathcad
14
folder to re associate DLL files, but it did not help.

Also did a repair of Mathcad 14 in Add or Remove Programs in
Control
Panel. That did not help either.

See attached Mathcad 14 file.

I hope the list still works. I have been getting 4 or 5 day
delays on
my submittals before they are posted on the Adeptscience web
site..

Bill

Product Reviews

"Our work ranges from complex medical imaging research to large-scale mapping and diagrams and we need a tool that is able to handle anything we investigate. With Mathcad, we are able to manipulate and analyse our data quickly while at the same time documenting our work, for sharing and publication. We also use it for pilot studies conducted in support of research grant applications. It is an end-to-end tool for research and development."
Dr. Kenneth Castleman, President of Advanced Digital Imaging Research (ADIR), Houston, Texas

"Mathcad is an integral product for my work... With Mathcad, itís easy to disseminate design calculations because the documents look like real math. Thereís very little I canít do in Mathcad. The main benefits come from the format, which resemble a typed set of calculations. These programs are easier to develop by engineers and easier for others to follow and review since the logic is expressed in a familiar manner. The format is what places Mathcad head and shoulders above other programs of a similar function."
Andre Pavlov, Structural Engineer, Florida Department of Transportation
