I have a cell array. When I use xlswrite to save them in an Excel file, it will lose precision at some decimal place. For example, if the cell is 191863214069, it will be 191860000000 in Excel.
What I want is to export data as exactly same as it is in Matlab. Anyone knows the solution?
Thanks!

You should not be seeing that. I tried the following and the Excel cell shows me the full value:
>> x
x =
1.9186e+11
>> xlswrite(filename,x)
When I open the Excel file I see the value of x with full precision. Maybe you didn't store the value as a double. Check the class of the variable you are exporting.
>> class(x)

Thanks. Well, I can see 1.9186e+11, but the point is the original should be 191863214069. I tried to convert it to multiple classes, but none of them worked...

Look at the cell value in the top cell and you will the value in full precision.
