This is an output formatting issue, and I will admit that it is 
annoying. Note:


gives zero. So, the answer is correct, it is just that Mathematica formats the 
output by rounding it. I am not sure how to make it show the way you 
want in an easy fashion; however, this works


but this is a formatted output "for your eyes only", i.e. DON'T do 
something like

b = NumberForm[ToExpression["109266.75"],10]

and then try to use b as a number.
