Matlab integer accuracy VS MS EXCEL

Hi All,
I am exporting my time series data from EXCEL to MATLAB as time series objects (fints).
Now after exporting, the excel figures -0.353344471286182 becomes -0.3746 in MATLAB fints table.
If it is rounding then isn't it too much? Can this issue be avoided?
this is just one figure, same is happening to all numerical figures.
Any help will be highly appreciated.
Regards,
AMD.

I do not understand why your title refers to "integer accuracy" instead of to floating point accuracy?

I don't have the fints() function, because I don't have the Financial Toolbox. However, by default, core MATLAB displays 4 digits, even though it keeps about 15 digits (double precision) for calculation. See
>> doc format
for some details on that. I don't know to what extent that carries over to the fints() function.
