"#" behaving like "0" in format (or ... pilot error?)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Value: 9876.0000000001
2. Format: #,#.###
3. Result: 9,876.000

What is the expected output? What do you see instead?

I had expected that the trailing zeros would be omitted in the output ("9,876") 
because at that point they are not significant digits. However, documentation 
is so sparse that I'm not sure if that is the expected output or if I'm just 
misinterpreting this as an issue.

What I see instead is what I would expect using a format of "#,#.00". That is, 
I see the same behavior from both formats.

What version of the product are you using? On what operating system?

Using the latest code drop from this site, on Firefox 3.6x and IE 6 over 
Windows XP.
Please provide any additional information below.

The more I look at this, the less I think it's pilot error. See examples at:
